Fuel Consumption

[Adrian Euro]

Hi Everybody I have a Honda Accord Euro 2003 which i bought Brand New. As time has gone on i Have put some modifications on and noticed that my KM per tank is declining with every mod. I was wondering what everyones KM per tank is. I have done a little outline. Looking forward to hear what everyone else is gaining.

Fuel Caltex Premium 95 - $94.00

2003 Car Bought Brand new - No Mods around 600Km per tank up to yellow petrol light

2005 Back Quater exhaust upgrade, same original size pipes from cat, two twin 2.5 inch tips on each side - 500km per tank up to yellow petrol light

2008 CAI Custom by Hypertune - 450Km per tank up to yellow petrol light

2008 Top Speed Headers, Changed original Flex pipe to Double braided flex pipe - 430km per Tank up to yellow petrol light

I dont feel that i am pushing the car more than what i did when i first bought the car.

Hope to hear everyone elses thoughts.

[defect]

more mods, more petrol?

[Adrian Euro]

more mods, more petrol?

Yeah i know that was just wondering a comparison to everyone else.

[tron07]

I avg like 10l/100km all the time... mostly town driving

Any mods? and also would that be around 600km per tank????

[Crapdaz]

order best to worst petrol IMHO
initially was
BP Ultimate>Mobil Synergy 8000 > Caltex Vortex 98 > Shell Vpower Racing 98

now
Mobil Synergy 8000> BP Ultimate> Caltex Vortex 98 > Shell Vpower Racing 98

2003 - 2006 -- no mods done shell did (400-500km), caltex (500-550km), mobil(550-650km), BP(650-750km)
NOTE: This is just a range of mileage that i have noticed when i drove the car as a daily driver with a couple of thrashings here and there.

2007 - 5zigen catback single exhaust(2.25" inlet diameter pipe expands to 2.5" throughout. w/ AEM SRI only use BP and Mobile (650km)
2008 - single catback, hi flow cat,sri, pulley kit, dc headers(4-2-1 single flex pipe at before the cat), etd, 100mm air feed pipe (steadied at doing 600-650km interval)

Hope this helps a little.

Mate they are good numbers with your mods. Maybe i am using the wrong petrol. Sucks for me to get 200km less than you per tank and you have more mods... there must be something wrong with my stupid car.

[aaronng]

km per tank is not a good way to determine fuel consumption. Do the full tank fill up method and calculate L/100km.

BTW, did you change your fuel filter at 80,000km? Have your spark plugs been changed at 100,000km?

Wouldn't have a clue would have thought mechanic would have done that for me as that was what i pay them for...

[Crapdaz]

yeh can't really determine by the mileage per tanks, need to calc per 100km.
i do average of 10L/100km.
Depends on how i drive.

if you havent done so, try change your fuel.
i am assuming you have been running caltex 95 all this time?

Cause i was running BP for almost a year and then i changed to mobil there was better fuel consumption per tank.

[aaronng]

Wouldn't have a clue would have thought mechanic would have done that for me as that was what i pay them for...
Check your invoices. Never assume that they will do everything. Good to check just to make sure that they are not ripping you off.

Fuel filter and spark plugs are big items. Parts cost of the fuel filter would be like $50-60 and the plugs about $90-100. Add labour on to that, and you should notice if your invoice has ballooned up by $150 or 200 when they are changed.

[racerwannabe]

I average about 10L/100km. My only breathing mod is a KN cold air intake. However, i do have 18" wheels and i think my fuel efficiency decreased after i changed my wheels. Do you have OEM or aftermarket 20"

What is your tyre size?

[Adrian Euro]

What is your tyre size?

Not sure...... they are federals though... use ot have nakang but they lost rubber really quickly

[aaronng]

Find out the tyre size of the federals and the tyres you had before. Could be the added unsprung rotational weight causing your increased fuel consumption.

by 200km???????? Like i mean Crapdaz has more mods by still gains more than what i had without mods?????? I change at around 3000 - 4000RPM per shift which aint that high...right????

[Crapdaz]

no its about right i sometimes shift at 2000-2500 as petrol prices are rising.
and atm i am running 16" stockies with stock dunlops. with 38psi so it is really noisy and bumpy.

Wow that interesting i put 42psi in my 18's and shift at that 3-4000. maybe i should shift lower.....

[aaronng]

Yes, heavier tyres have more effect than mods on fuel consumption, (except the ebay chip. ebay chips will increase fuel consumption like crazy).

3000-4000 for normal driving is considered high. I shift at 3000 for the first 3 gears and then 2500 for the remaining 2. 6th is only for cruising on free ways.

[Suntzu]

My fuel consumption has improved a bit since my mods. The biggest difference was the Jtune reflash, but bear in mind i have to use 98 ron.

I recently got 800km from a tank, could have done better but i dont back off. Also got an average of 5.9l/100km 2 months ago on a 100kph average trip.

Im averaging about 7.7 l/100km which is about 740kms a tank on 100% highway sitting on about 120kph in 110kph zones.

In town im a lot heavier with the right boot and am getting 9.5 l/100 going at it enthusiastically. I think a town rate of 8.5 would be easy.

The euros great on fuel. I do run 40psi in the fronts 38psi rears, im lowered, I have a comptech CAI and headers and a hi-flow cat plus mild Jtune.

At these consumption rates I can'y justify selling my car and getting a diesel.

mate thats heaps. How much would you get within traffic? for a full traffic no freeway driving???? Did the mild tune really get you that much gain????

yeh duno how you can get such good fuel economy, but then again your in canberra. Never as bad as Sydney. The most i did was to and from to port macquarie which was like approx 1000km(total trip) on one tank, but i was too afraid it'll run out so i filled up.

[Type R Positive]

I have to read my manual, because this new CU2 is supposed to have shiftlight to tell you when to shift to be most fuel efficient. I'll have to post my findings....

[Type R Positive]

CU2 has that feature built in now!!! Man, this car has all sorts of bells and whistles. :p

[Suntzu]

Canberra is heaps different to sydney.

Firstl I work from home, so I drive in the 10 am to 4 pm range = No traffic

Secondly Canberras organised and smooth so the flow on is better.

if i really flog the jesus out of my car in town it will use 10.5 l/100 no issue. But NEVER higher.

It will consistently do 7.5-8 l/100 highway at just above posted speed. At posted areas of 100 kph and if you do 100kph it will do 6lt /100k with no air con on. It jumps about .5 lt/100 with air con.

Theres a massive difference between 100kph in the euro and 120 kph average. Trust me.

It town it totally depends on your driving style, mines a bit "fun" so i pay a lot more that i should. that being said it s massively better than my old magna sports 3.5 which was 15 l/100in town with the righ boot buried and no quicker than my euro.

I rely on the correct method for calculation as i dont have a computer in my 2005. Fill tank, drive and measure KM, fill tank again and get EXACT fuel used. My trip computer in my 2007 CRV Lux is never correct either thats why I use the proper method.

edit: Crapdaz: i beleive the euro manual is easily capable of 1000km per tank if you are careful and lay off a bit. My calculations show this can be done easily though I have never done it.

[aaronng]

I live in Sydney with the fun jams.
For pure city driving, I get 10.5 L/100km.
For pure freeway driving when I do Sydney-Melb, I get 7.0-7.2 L/100km.
For my recent combined consumption where I hop onto the M4 to work and back, which is 1/2 the time on the M4 and 1/2 the time on Prospect highway+sunnyholt rd, I get 9.4 L/100km

So pure city driving you still get around 570km. I drive from city to sutherland shire everyday around 60km each way up the princes highway in heavy traffic in peak hour times and i only get 430km now. I am so spewing its not funny. Its costing me a mint.

nice nice, good to know canberra is the place to be to save fuel.
last time i visited last year i noticed there is no crazy sydney like driving.
but what i dislike are those massive roundabouts get lost sometimes.

This is one for the technical gurus to comment on, but I've heard in the past where Commodores have had fuel consumption issues it's come down to faulty oxygen sensors. Does the Euro engine have these sensors? I'm not up with the mechanical details of the motor so don't flame me if I'm way off track here.

[EuroAccord13]

It doesn't just happen to Commodores. Any cars with 02s will be subjected to these conditions in the 02s.
What happens is that with age, the combustion and soot in the exhaust can build up in the element and then cause the 02s to respond slower to changes in th A/F. The sensor's voltage output can also drop and thus giving a leaner A/F ratio than normal so the ECU will start pumping more petrol in and hence increasing fuel consumption.

[aaronng]

So pure city driving you still get around 570km. I drive from city to sutherland shire everyday around 60km each way up the princes highway in heavy traffic in peak hour times and i only get 430km now. I am so spewing its not funny. Its costing me a mint.

How much time do you spend in the car with the engine running but the car stuck at 0km/h? That's the worst culprit that causes high fuel consumption.

Yes it does have O2 sensors. If you get silly high fuel consumption while on the freeway, then it is the O2 sensor.

[EuroAccord13]

Here's a tip for saving a bit more petrol, don't put the car in neutral when you are cruising to a stop, leave it gear and downshift accordingly. This will make the ECU inject minimal petrol to keep the car going as opposed to leaving it in neutral where it will be injecting more petrol to keep the engine running at idle although you are still in motion.

[Type R Positive]

yeah but 119ks on my euro speedo is only 113ks according to my gps..

i wouldnt do 100ks on the speedo when the speed limit is 110ks.

having said that, ill get 600ks out of a tank when driving back from perth (450ks) and then around town the rest of the tank in my oem 04 lux.

Round town(Sydney)get 8.2-9L,on the open road have had as low as 6.5L.BTW mines a manual.

[SPQR]

It takes me two minutes to drive to work but more importantly, only two minutes to get home after work. I have been getting 10.5 l/100km in suburban and city driving in my 04 Euro AT. I get around 11.8 l/100km when I'm having more fun.

I worked in Sydney briefly (on transfer to Sydney office on the North Shore). I was amazed that most of my colleagues would have to commute up to two hours to work and the same back home. That's four hours a day of their lives wasted every working day. When did they get time to live their own lives?

The average fuel consumption meter on my 07 CRV AT is not accurate. It is usually quite optimistic in that it under reports the actual average. Don't rely on these meters. Do the proper calcs as aaronng says.

The fuel light comes on at a slightly different level to each car! Then, you have a problem where different petrol stations fill up to different maximum levels. It is not consistent enough to compare kms per tank. Go and fill up til the pump stops, drive 100-200km, then fill it up again at the same station and calculate. Then your number will be comparable to all our numbers.

[EuroAccord13]

The flow of petrol in which you put into the tank will also determine the actual number of litres you put in....
The slower you pump the petrol in, the less the petrol will vapourise and become gas.
If you pump petrol in fast, you will not be getting the actual amount in liquid form.

Tiny tiny difference..... less than 10ml difference I am guessing.

and then you gotta consider also that when you fuel up your mixing petrols if your changing fuel (e.g from BP to Mobil), and each batch of fuel with have slight variances. :wave:



Tiny tiny difference..... less than 10ml difference I am guessing.
could be the difference of a couple of dollars soon enough from petrol prices sky rocketing.

[EuroAccord13]

More than that, you'll be surprised that you can end up losing a lot more than just 10ml.... Can't remember the actual rate of loss but from memory the vapours can take up a fair bit....Add that for a month and that is still some money vapourised....

[aaronng]

Yeah, but the slight variance is still smaller than compared to when a pump stops filling at full tank, or when the fuel light comes on each car, or the driving style of each individual.

Assume you lose 10 times the amount that I claim, so 100ml. When petrol hits $2.00 per litre, that means you are losing 20 cents per fill up. That's less than if you decide to fill your tank at a petrol station advertised at $2.00 per litre instead of $1.99 per litre.

More than that, you'll be surprised that you can end up losing a lot more than just 10ml.... Can't remember the actual rate of loss but from memory the vapours can take up a fair bit....Add that for a month and that is still some money vapourised....

Okok, if you lose 100ml (which 1/3 a can of coke) per fillup, then at $2.00 per litre, that's 20 cents. How often do you fill up a month? 4 times full tank? That's 80 cents lost. Compare that to other things, like ciggies. hehehe. A stick costs 50 cents each (from a 20 pack costing $10). Just smoke less 2 sticks a month and you're ahead by 20 cents! muahahahha.. i'm evil.

[EuroAccord13]

Based on 200 litres plus a month for me, I will be saving 40 bucks a month JAJAJAJAJAJAJA!

[aaronng]

Based on 200 litres plus a month for me, I will be saving 40 bucks a month JAJAJAJAJAJAJA!

You lose 100ml per TANK. Not per litre. So if you fill up 4 times (50L each time), you only lose a total of 400ml, or 80 cents per month. (unless you fill your car 1 litre each time)

[EuroAccord13]

Opps my bad......

[Crapdaz]

rofl this topic has gone crazy!! hehe

[Ramzes213]

Hi Fellas, I think U are doing really well with consumption of your euro. When I started reading this topic I nearly panicked and nearly put my Accord V6 for sale, because of fuel consumption. It was until I read one of the posts where (i think Adrian Euro) said that in heavy trafic he can do only about 430 kms per tank. That was like relief for me. I live in Melbourne and usually drive to work and back. To get to work I do only about 7 kms just accross the city. So I start the car and than usually stop at every second trafic lights, so I do only city drive. From my calculations my V6 takes about 15l per every 100km I do. So It is not that bad with my V6. But your figutes of 7.0l per 100kms outside the city are impressing.
Good luck.

CL9 As my Euro is the standard car it doesn’t have the fuel usage rate readout. I am curious what the usage rate is at different cruising speeds. That is to say at 90kph, 100kph and 110kph. I would be thankful if one of you forum members with the lux version could take readings at those speeds and report back. Thanking you in anticipation

[Crapdaz]

if your mainly doing highway you can reach from 6-8l/100km depending on how many times you stop.

e.g hill climbs & start/stop traffic

NOTE: This is only a rough estimate.
when i did my trip to port macquarie i did about 1000km @ 56litres (when light comes on) = approximation as i lost my fuel receipt and didnt calculate. --> 5.6L/100km Trip included To + From + Driving around @ Port. (Also filled up before i left incase of getting stuck in traffic which we did and a side note the fuel needle was above middle)

[falco]

I have a 2003 Auto I purchased new. When it was new I was averaging 8.1 l/100k now its up to 8.4l/100k
For me; Caltex petrol seems to give me the best results. Shell the worst.
NO mods :angel:

[Crapdaz]

have you considered BP Ult or Mobil 8000 btw i have 2003 Manual Lux - falco

I found Mobil 8000 last longer for slightly less perf > BP ult
But BP Ult has better response > burns slightly quicker than Mobil
These two are about 550-700km depending on driving & mods.

Caltex Vortex98 is better than Shell Optimax/V Power & Racing by about extra 50-100km depending on driving.

[ROBERT]

Thanks guys but I am asking for the consumption at STEADY CRUISING speeds NOT averaging over a run. I keep an acurate fuel consumption log and averaging 7.3l/100k since I had the car new, my best is 6.3l/100km on a run down from QUeensland.

the only way you can get a decent run is if you drive from 1 servo w/ full tank & zero'd tripmeter then fill up at the next coming servo and check it out to calc. But still averages around 6-8L/100 no matter for highway driving.

There is no way you can check otherwise.

[ROBERT]

I realize that very well, I believe the lux version has an instant readout of consumption. I am asking WHAT ARE THE FIGURES FOR STEADY CRUISING at 90, 100, and 110kph.

[Suntzu]

When are you peeps gunna realise the trip computer is optimistic and you need to look at fuel going in and actual KM completed at fueling stage? sheesh

[ROBERT]

I repeat, I know what my overall consumption is on a trip as I ALLWAYS record litres put in and the oddometer reading. I record all this including cost per litre and put it on a spread sheet. I am asking for the cruise readings to get a comparison between the different speeds. I also know it will be optimistic, but it is the DIFFERENCES between them that I am interested in.

[Suntzu]

My fuel consumption is improving now I have the RBC. I dont know why. Maybe its leaning it out. Its enough to be noticeable. I cant believe how good my car is on fuel. Its astonishing considering how i drive..

City I get 9.2-9.3 L/100 indicated on the trip computer, average speed usually records around 30-40kph.
Highway at steady 110 cruise I get 7.2-7.3 L/100 indicated on the trip computer. Cruising at 100 instead of 110, the lowest I've seen is 7.3. Hills seem to affect this figure more than the speed does, if I'm staying in 6th gear.

That's pretty good, how much on your odometer?

[HunterZero]

Errr... 6,700km... *looks embarrassed...*

And I drive like my grandmother... If I do give it a bit of stick once in a while, it pushes the city economy to 9.4-9.6.

And I don't do a start-stop daily commute, which is probably why I get a decent city economy.

yeh i want to find out how much my car pulls stock now....or with stock box + stock exhaust.

Aaron - do you have a van/trailer i could borrow to transport my exhaust?

[dtngo]

I've only purchased my (second hand) Euro and have gone through two tanks of fuel. First tank I got 9.2L/100kms, second tank I got 8.5L/100kms. I am using the fill - drive - fill - calculate method. Both tanks on Optimax.

[HunterZero]

Both tanks on Optimax.

Welcome to the owner's club! Nice car, innit? Manual is great, definitely good for fuel economy.

Where are you getting Optimax? ;) Or did you mean V-power?

I think people here seem to prefer Caltex Vortex 98, BP Ultimate 98 or Mobil Synergy 8000 98.

I use BP because it's convenient. It seems to have very little exhaust dust. Very clean fuel.

- HZ

[buddah51au]

I will copy my spreadsheet on fuel consumption here as there is not a lot to copy at this stage. I will add that i have filled up at the same pump each time (Vortex 95) until fuel is visible, in other words totally full. what i do find strange is that I have yet to see the low fuel light come on so I do wonder what the actual capacity of a CU2 fuel tank is. You will notice that the first tank does not compare with the rest, i put this down to the dealer not completely filling the tank.

lol yeah I'm used to calling it Optimax from the old days. It's handy cos there's a Shell near my house (West Ryde), one near my in-laws (Fairfield) and one near my parents (Cabramatta). Also use the 4c discounts too haha!

BP has always burned too quick in my old car (NX Coupe), but have yet to try it on the Euro. Might try Vortex 98 next (Woolies 4c discounts!), but no Caltex servo's around here and the one in North Ryde is always jam packed:(

[HunterZero]

I used to use Optimax when it was branded Optimax in my last car, and it was a good fuel... But at some point not too long before it changed to V-Power brand, I think they must have changed the fuel, and it didn't give as good economy or as sharp throttle response. So I changed to BP Ultimate and it was a great improvement.

I hear people still complain a bit about V-Power not giving them quite as good economy as the other three fuels, and dirtier exhaust. And V-power racing is E5, so I wouldn't buy it over non-ethanol 98RON.

Definitely give the other three fuels a try if you ever cruise past one of those stations.

Comes down to whatever is convenient. But there is a Mobil on Victoria Rd at West Ryde and on Lane Cove Road at North Ryde.

- HZ

[Crapdaz]

imo i think BP does burn quicker but ends up running your car smoother.

optimax, vpower, vpower racing all got 400-450km when i was stock.

[Ken-f]

Thats terrible. I think most ppl get about 600-650 a tank stock

[buddah51au]

I have redone this to make it easier for you all to read. I can easily exceed 800km per tank without low fuel light coming on consistently. If you wish to log accurate fuel consumption figures may i suggest making a spreadsheet similar to what I do. No guesswork, just 100% accurate figures.

[sdablhad]

I have used BP ultimte since I got my euro 18months ago.

City driving (in a small country city) never more than 10L/100km - ave of 9.5 i'd say
Counrty roads and freeways down to 7L/100ks

this is in a stock 05 auto euro with a/c on all the time. I agrees with Crapdaz, and would say in the right conditions I could get 1000+kms from a tank. though I would never let the tank run down that far and get tank scum in the injectors.

[ig3o]

i use v-power.. and i have these mods

injen CAI / metal cat / 5zigen proracer catback

if i drive normally and shift at 2500rpm.. i get about 610km until the yellow light pops up

[ningnong]

Hello Gents (and Ladies).
I have a 2005 Euro 2.4 auto standard with no mods at all. with 37 000km. I average about 10l/100km in traffic, and have not taken her on the open road yet. I use mostly either Mobil or Shell 98 RON. with tyres at 36psi front and 34psi back.
I'm looking to improve performance and economy without busting the bank and/or pissing the wife off. I was concidering a K & N Cold air intake. Any other suggerstions, please?

[djpro1]

I've got intake/catback and it hasn't affected my fuel consumption at all. in fact, i just went to jindabyne (450km) from Sydney yesterday using about half a tank :D

[ultimatekenz]

Im getting terrible consumption compared to you guys...
Avg about 11-12//100km city.

[SPQR]

^ Pretty good for a WRX. Astounding for an R32. About what I get in my CL9.

[buddah51au]

It is some time since I updated my consumption figures. My CU2 Auto is averaging 7.1 over 30,000km. One of the advantages of country living.

[aaronng]

Im getting terrible consumption compared to you guys...
Avg about 11-12//100km city.
11-12 L/100km in the city is spot on. Most of us do combined where we have a little bit of 70-80 km/h roads which brings the consumption down greatly.
For me, City was 11 L/100km, City + a bit of 80 km/h was 10.5 L/100km, Combined was 9.6 L/100km and pure 100km/h freeway was 7.1 L/100km.

Funny thing is the wrx used more fuel then the gtr. I was getting about 250-300km from a tank whereas i could get about 350-400km in the gtr. The wrx was fairly modded...

Oh ok. Just needed confirmation that these numbers were normal cos i read in another thread someone thought 12l/100km was an issue.
Thanks for the replies.

[Nairda]

Currently trying Mobil Premium 95. Getting 8.1L/100km. Conservative driving to and from uni and church. Usually do between 100-150km a week. Much better than the United E10 my dad was running it on (8.7L/100) and tons better than Vpower that i tried the last fill up (9.2L/100). BTW im not kidding i also drive CL9. Are you guys thrashing it a bit?

Oh i forgot to add, i only find myself sitting in a traffic for 30 minutes once a week. every other time its smooth sailing constant average probably 60km/h

If you're only in traffic for 30 minutes once per week, of course you're going to get better results than most CL9. And going to church is clearly giving you a fair advantage over heathens, lol!

[whteva]

i was getting just over 600km but just done a main services so fingers cross i can get some higher figures that i been reading here.

I miss mine too, especially the feeling of being forced back into the chair after 3000rpm and a cool 20psi of goodness...

[minircc]

CL9 Euro Luxury Sports 6spd.
Stock with K&N OEM replacement.

I drive to work everyday to Melbourne CBD in gridlock traffic for around 20-30mins depending on the day.
Then on weekend, i do some free runs. Average is 8.5-9L/100kms.

On a trip from Melbourne to Adelaide and back, I managed 6.8-7L/100kms. 110km cruise control most of the way.
750kms and still a small block of fuel left.. i was amazed. you could do one tank the whole way. but i filled up 100ks into the trip.

I normally shift between 3,000-3,500RPM.
I find changing too low RPM just bogs down the engine and uses more fuel.
eg. sitting at 6th gear at 60km/h.
if it's there's a slight down incline, then maybe. otherwise keep it in 5th.

[SPQR]

Yep! I used to save lots of money in my WRX; I'd find most of the coins that were in my trouser pockets on the floor behind the driver's seat: No money in pocket: No spend.

[ningnong]

Have just taken her for an open road 1400km run with two people and a boot full of junk. Generally was driving 10 -15 quicker than the limit on cruise controll and air con off. Tyres at 28 PSI front 26 PSI back running on 98 RON. She got 7.2 l/100km. But still getting 10 l/100km in gridlock Sydney traffic driving carefully.

Just took my Euro for a straight run from Gladstone to Brisbane with one passenger and 50kgs of luggage.
Full tank of BP 95RON, tyres 35 psi all around, aircon on probably half the time (3hrs), 5A and cruise control only on around traffic.

I got 7.4 L/100km over ~500km averaging 93km/h (damn roadworks ruining my average speed D=) from the trip computer.

This was on a mix of mostly undulating country highway and some smooth motorway travelling at a minimum of 100km/h...was pushing 140 or so for a good hour on the Isis Highway where you'd be lucky to pass another car let alone a cop! :p

2010 Accord Euro auto 11.5L/100kms Caulfield to city everyday, no mods, 35 PSI all around, Caltex 95
2007 Civic Hybrid 8.9L/100kms Kingsford to rose bay everyday, no mods, caltex E10

Question: how do you guys get 8.5 -9.5L/100kms on Euro? Even the hybrid need more fuel than the euro. isn't it insane...

[chuboy]

Depends on the driving style. For cruising it is really down to aerodynamics and how well your engine and gearbox is tuned for high-speeding running. In the city hybrids dominate as combustion engines are woefully inefficient when accelerating. In the city, vehicle mass makes a big difference as your engine has to work harder in order to acheive a greater momentum for a given speed.

Hybrids versus an otherwise identical non-hybrid car will lose out in highway driving because of the weight penalty, but vice-versa for the city. Hybrids are out of their element once you leave the city!

8.21 is the worst I have ever recorded & that was on the first tank from the dealer, so obviously it was not completely full. every tank since that time has been between a best of 6.03 & a worst of 7.54.

I can get that high I reset the trip computer while I'm doing some lead-footed city driving..

Otherwise something's a bit unusual.

[rayd17]

chuboy; yeh i might have to add a bit of details !!!

car uses caltex 95.. some people are complaining it isnt really good...
my driving is revving no more than 2500rpm.......
service was done 3000kms ago .....
11.5 is ridicolous and the car only has 65000kms on the clock so its not overly driven.

in comparison, had a bmw 120d.... it used 8.5L/100km and same style driving (to the train station how embarrasing) and it used to get a boot especially with the 340nm pulling power.

any ideas from the honda community? i love the euro, it has such good features but im a bit let down on fuel consumption :(

[chuboy]

That sort of consumption does seem unusually high, do you notice anything unusual about how the car drives? What tyre pressure are you running? Have you always got that kind of consumption?

For me the most I ever get over a long period of city driving is probably ~10L/100.

in all honesty bought the thing last week :P always serviced at honda... this person was the type that just paid honda to do everything not even change a light bulb himself.. mind you the mats are dirty so he has used it well. body of car is in good condition paintwork is awesome ! its the pearl white...

i will update everyone when i get to use this for "non station runs" !!! and see if the fuel settles down.

tyres are yokohamas with 75% tread, running at 34psi. i checked.

im thinking now it could be the caltex fuel in the end its woolies .... hopefully it is actually 98 vortex they are selling me :S

**diesels are honestly by far getting very popular and really good in both power and economy im sure the euro will see a diesel variant very soon. bad point is they know everyone is getting a diesel and jack up the prices...
bmw was my parents. im thinking i should have loaned some money and bought that off them now :S

[chuboy]

Lol give it a long run on the motorway somewhere and you should get no more than 7L/100, probably closer to 6. Any higher than that and something is up. I drove from the Gold Coast to Brisbane with a fully loaded Euro and trailer attached and I still got about 7L/100 so it is an economical car.

[buddah51au]

The majority of it is country driving granted, but for the last 4 months I have lived in the center of Hervey Bay which is quite congested at times with a lot of 50kmh speed limits. in saying that I use pedal power a lot now ..... lol

I have used 2 tanks of Shell V Power & 2 tanks of Vortex 98 since I have had the car, & it makes no noticeable difference to power or economy than vortex 95 which is what i normally use

People need to take note of Honda's advise fuel consumption - 12.3 City Cycle, 6.9 Country Cycle, so if your purely driving in the city i would suggest 11 to 13L / 100, depending on how much stop start driving you do, or how much driving u do on a cold engine.

no worries buddah, its early days of me owning a cl9 so see how we go. otherwise its a marvellous vehicle; ive been quoted 500 km out of 68 litres of a falcon xr6 city driving which sits it at around 12L/100 .... makes u wonder if these 4cylinders are economical just for pure city driving unless i downgrade to a freakin yaris :S or getz before u start seeing 7's ? can anyone back up the quoted value ive asked from others ?

if we can afford a euro we can afford the fuel put it that way ! by all means i dont degrade the euro. its a different class of car that we all have to appreciate ! quality/handling/decent power and its kit is all comparible with european.

btw * your euro is doing very well fuel wise ! good car you got there :)

[Fredoops]

I've got a cl9 euro (AUTOMATIC) for 7 years now. Lived in metro Sydney and Brisbane.

Fuel consumption for metro city driving was always 9L or more. It'll get progressivelly worse as the car ages.
Currently it's drinking 11L in city driving now for me for the last few weeks. But I know it can spike to 12+ I you use aircon or thick engine oil.

Manual will be a lot better, especially a car ages.

[TurBIce]

Mines a auto cu2.
I get about 10-11L/100km

But when I use that manual mode thing and shift at higher revs. I get better economy.

[05accordeuro]

Hi guys,

I own a 2005 Euro, and the fuel consumption was quite horrible to say the least, about 450 a tank with no mods at all (premium 95 used). Then I took it in for the 100K interval which is all new spark plugs, filters etc, and now im getting about 650 :)

So check to see if you got new spark plugs would be my guess :)

A lot of factors there, like thinner engine oil, new/clean air filters, reset ECU (this is a good one).... lower resistance tyres etc etc etc.

I found my car drink less and runs better after switching from 10w-40 to 5w-30 engine oil, I'll try 0w-40 next time tho for better cold protection.

**** I hate Sydney traffic!

i've been getting about ~550Km on a full tank using 98 RON.
suburban and abit of freeway (~4km)
only mod i have installed is a injen CAI. (could this be a reason?)

normal or am i just expecting too much?

Downgrading to a smaller car may not be as beneficial as you think. Prior to owning my CU2 Auto I had a FD1 Civic Auto and over 60,000kms I averaged 6.83 L/100. If you compare that to 7.08 from my Euro it is under 0.3 L/100 - that's same driver, same conditions. Draw your own conclusions.

If you use Honda's advertised economy for city cycle I believe you would have to drive very conservatively to get under 11 L/100 from a CU2 in city driving conditions

What model, year, auto/manual, tyres?

[jono_l]

Have a 07 CL9 auto here, stock, 70000km, run on 98RON.

Averaged 11.6L/100km over the last 8000km (so approx 560km/tank for a 65L tank). 90% of the time the car is driven either in a peak hour traffic jam (Victoria Road for all you Sydneysiders), or making short (15 minute) trips to the station via backstreets. Whilst the fuel economy isn't great, I'm not too surprised, as I don't try very hard to conserve fuel either.

2010 Accord Euro auto 11.5L/100kms Caulfield to city everyday, no mods, 35 PSI all around, Caltex 95
2007 Civic Hybrid 8.9L/100kms Kingsford to rose bay everyday, no mods, caltex E10

Question: how do you guys get 8.5 -9.5L/100kms on Euro? Even the hybrid need more fuel than the euro. isn't it insane...

8.9L/100k for a civic hybrid!?!?! get that thing checked out!! lol

i run 18x8 and 18x9 SSR viennas 39psi and the highest i get is 5.6L/100k

[buddah51au]

I have posted these pictures before. they were taken on a trip from Central QLD to Sydney. Easily recognisable by CU2 owners. Over 1000km on a tank if petrol stations are in the right location. I checked my spreadsheet & I finished up refueling after 989 kms.

I've been getting 8.0lt/100km oO been getting about 740-800km off a tank, 34psi on all 4 wheels and BP 98 ultimate

Driving from station > home via backstreet and the occassion trips to the city and westside on weekends but mind you, driving on weekend nights is no different 2 driving in peakhour =="

i recently got my 05 euro luxury manual stock filled up 55L bp unleaded 95, drove till warning light came on filled again was 54L distance travelled 674km, so consumption would be 8.3L/100km?

driving to work on 60/80/100kmh roads, lead foot few times, hopefully on this 2nd tank i can lower it since im use to the car now hehe xD

54 litres divided by 6.74 hundred kilometres = 8.0118 L/100km.

For those that are interested; in the old-ancient pre-1971 measurement: 8.0118 divided by 4.54 (litres in an Imperial gallon) = 1.7647 gallons. 100km divided by 1.6093 (km in a mile) = 62.139 miles. 62.1389 miles divided by 1.7647 gallons = 35.2 miles per gallon. Or you can use the constant 282.2 and divide by the L/100km i.e. 282.2 divided by 8.0118 = 35.2 miles per gallon.

I don't know why we use L/100km. Why not km/L? Surely most people would rather know how far they can go on each litre of fuel. In this case it would be 12.5 km/L. So if you'd estimated that your car had 10 litres of fuel remaining, you could easily calculate 12.5 x 10 = 125 km range.

If you like to play with figures try this from my CU2 Auto - 989kms / 61.63 lts

On my current tank I have 879kms & the low fuel light is not yet on / last fill was 11th April / average speed on this tank is 85kph.

o.o man ur lucky :( to be that fuel efficient LOL

[Xplodin]

That's cos his mainly freeway driving... His average kph is 85km/h.

[buddah51au]

Sorry to disappoint you mate, but there are no freeways where I drive. I will add that for 300km on my current tank the car was fully loaded with helping someone move. I could not have fitted anything more at all in the boot, the back seat was loaded almost to the roof & 2 full milk crates tied to passengers seat.

For those of you that know QLD, the current tank is 3 trips between Hervey Bay & Gladstone, so about 85% on the Bruce Goat Track.

Bruce is still a highway, with load or not at 80-100kph it's always the fuel consumption sweet spot, especially with CU2's gearing. Your consumption will always be significantly lower tha us metro folk.

[buddah51au]

Sure, driving the Bruce Goat Track will give better consumption than driving in the city, but it is a poor excuse for a hwy. Potholes & roadworks everywhere makes the trip a pain in the butt. Don't forget the Gin Gin Range kills fuel consumption. I have already lost 1 rim to a pothole, so night driving is a big no no at the moment.

A major problem for Metro driving is the Auto wont pick up top gear below 75kph.

Picked up my euro and drove it from act to melb, 7.008l per 100km. Impressed.

[euRo_noob]

I was at 9.4 L/100km for a while but just recently it dropped to 9-9.2 L/100km and I had to disconnect my battery for my intake yesterday. Now I'm gonna try keep it under 9 L/100km! I get roughly 700-750km with a full tank. 6MT MY11.

[falco]

I am getting around 10 - 11 L/100k around town driving. When I phoned up Honda dealer complaining of high fuel consumption they said a major service will fix all my problems. It will only cost me $700

I get 600km from full to light on I have a full exhaust CAI, I have an accord euro CL9 2003 - I drive about 700km's a week mixture of city and highway driving. I use BP Ultimate or Mobile 98

Lol.... Here's what you can do for a lot less than $700...

1. Change to thinner, full synthetic oil
2. Complete injection system flush/clean, $100 -150, if your cars overs 7 years old.
3. Pump up them tyres
4. Weight reduction, get the excess baggage put.
5. Clean/change air filter to something performance oriented.
6. Use 98 octane (caltex/BP instead of crap shell sell)
7. disconnect battery to reset ecu.

[trism]

I disagree. Going from BP Ultimate to Shell VPower got me an extra 50km per tank.

2006 AT Euro, with exhaust mods, K&N filter and brand new tyres. Surprisingly the fuel consumptions been up ever since the new tyres, maybe thats because my wheels are larger now. Best I've got is 11L/100 but this is pure city driving with no highway/freeway whatsoever. I guess this is alright considering im getting 15-16L in the lexus....I've heard that installing coils will improve fuel consumption because less energy is lost to the softer damper/springs while accelerating...is this true?

And the cost of those coils can buy how much petrol? :-p

If anything I'd get a lighter pulley...

[Razer]

haha Ive got coils already, and I didnt get them to improve fuel consumption if thats what you're saying, I got it for a better driving experience and reduce the "boat" feeling that the euro has when turning. Either way Ive got UR pulleys as well and I might add the pulleys did improve the fuel consumption by a lot. The cars got torque from as low as 2000rpm nowadays so theres no need for the car to work as hard as before.

[euRo_noob]

Quick question: If I still have about.. 1/4 of just normal unleaded petrol in my tank and I wanna switch to BP Ultimate/Shell V Power, do/should I wait until I use most of the petrol that's already in the tank first before I refill or can I just pour in the BP/Shell now and it'll be mixed?

Define "normal petrol", you should already have at least 95 in the car so it's alreay premium, so mix away.

Oh yes, I meant unleaded 95. Also, how about unleaded 91? 91 is a definite no for our cars? But anyways, so should i wait until most of my petrol is gone before I refill or is it safe to just mix the two together?

Thanks

[Kevl]

Have started to pay more attention to the trip computer now and average fuel economy tends to be 12.0-12.5L / 100kms. Mostly city driving.

This seems to be more than most people on this forum (2006 CL9, Auto). Just had a recent service at Honda as well.

Usually use Caltex 95 (only BP has 98 in NZ).

Anyone else have similar fuel consumption? or any suggestions to improve?

(on a side note, the fuel tends to splash out abit now when I've got the pump at full pressure, haven't tried another pump yet so that could be the issue but anyone else have this problem?)

[adis]

Mixed everyday driving, im getting constant 8.3-8.4 L per 100km.
Im bloody happy!!!

Has anyone compared true fuel consumption (that is calculating actual fuel used against distance travelled) against what the cars readout says? My CL9 is the standard, so no readout. I suspect the cars readout would be optimistic.

[Kevl]

Have not done that before (because I never fill up the car) but remember reading in a review that it was a bit optimistic (like on most cars)

[buddah51au]

On the CU2 the readout is generally 0.3 to 0.4 below the true figure when you work it out with a calculator. example - indicated 6.4 is 6.7 to 6.8 true.

[seanneko]

I decided to do another comparison between E10 and 95. After running a few full tanks of 95 to reset the ECU, this is the economy I got (calculated using the trip meter and the litres displayed on the petrol station pump after filling):

E10 - 7.65L/100km
95 - 7.62L/100km

Driving style was the same on both fuels - approx 80% highway, 20% city.

I'll be changing back to E10 again. Waste of money paying extra for 95. It's no smoother, gives no power increase (at least not enough to be noticeable by a human), and gives identical economy.

[opilot87]

You should probably average over a few tanks of fuel to get a better idea me thinks.

E10 what exactly? The coles/woolworthes e10? Dear God I'm hoping you're not doing that. You'll kill your engine REAL quick with e10 93 or 91's. Scientific fact remains, e10 contains less energy compared to full petrol.

And which 95 were you using, just remember not all 95's are 95's...

And your feel economy will almost always improe when you reset ecu. The only way or you to do a proper comparison is on a racetrack or provig ground with identical cars.

[buddah51au]

[QUOTE=opilot87;3021740]You should probably average over a few tanks of fuel to get a better idea me thinks.


I agree, you should definitely average each fuel over a minimum of 3 tanks. eg - my last 3 tanks driving the same roads with same driving style = 6.53, 6.79, 6.95. A negligible difference I know, but fuel consumption needs to be averaged over several tanks to get a true indication. The best way is to make a spread sheet & update it each time you fill up, in my case 37,537km / 2655.37 lts. It is so easy to get a long term accurate average.

The only E10 in Darwin is United and supposedly 95 RON. I didn't know it came in lower RON. Honda advises that E10 is OK for Euro. But, having said that, I don't use it.

Shell E10, which according to the pump is 94 RON, and Shell 95.

I did run through 3 or 4 full tanks, and noticed no difference between any of them. After the final tank I got a figure which was 0.03L/100km less than what I initially got on E10, which is probably nothing to do with the fuel anyway, and simply because the driving conditions can never be 100% identical.

[Fredoops]

You shouldn't be using anything less than 95 in the euro anyway. it voids warranty pretty much instantly.

Keep running e10 and see how much corrosion damage can be done in a year, while the knock sensor of the euro will prevent immediate damage to the engine (blown gasket etc), over a longer period... It will speed up wear/tear/corrosion of engine parts. And all ethanol fuel contanl 4-5% water. Because pure distillation isn't possible.

Sooo, for a 60 ltr tank filled with e10, you have 360ml of water in your fuel.

The performance deficiency is compensated by resetting the ecu, because engines buns much leaner when you reset ecu, it takes a long while for ecu to 'settle down'

Why would E10 cause any corrosion damage at all, especially when Honda Australia specifically states that all Accord Euros (as well as most Hondas in general) can safely use E10:

http://www.honda.com.au/cars_for-owners_ethanol.aspx

The only condition is that it needs to be 95 RON minimum, but there's really not much difference between 94 and 95 RON, especially in a stock Euro.

I'd like to see some actual proof that using less than 95 RON in a Euro (specifically CL9 - I know that some CU2 models would ping on certain fuels) will cause damage. One thing I've noticed about the Honda community is that there are so many myths with no actual facts behind them. Another which comes to mind is that you must use genuine Honda auto transmission fluid, but nobody is able to explain why this is the case, or what will happen if you don't.

Honda Australia advises E10 fuel with a RON of 95 or above is safe to use in all Euros. The fact that there is less energy per joule of ethanol than octane has nothing to do with it damaging your engine so long as it has an ECU... it just means you need to burn more fuel to get the same amount of power.

91 fuel is a no-no as a rule but in a pinch you can get away with it.

EDIT: 360mL of water in 60L = 0.6% water. Negligible considering that exhaust gas is 31% water by weight...and the intake air is not going to be at 0% humidity...

Also 95 fuel is required in order to meet ADR standards for emissions and so forth, as well as meeting advertised performance, and then of course to minimise engine knock. As for genuine fluids...Honda mechanical engineers designed their components and when they did that they made assumptions about the chemical and physical properties of the lubricating fluids. So then they said to the Honda chemical engineers, "make us a fluid that has these properties". So they did, then they sold it.

They don't recommend using anything else because they can't be sure it will do exactly everything it has to.

Honda ATF is DEX 6 or something made by Newmarket, so it is cross compatible. Honda OEM PS fluid however, has a unique anti frothing agent, to prevent damage.

The problem with testing fuel, is it's long term, so I guess your car will be our test bed on the effects of long term ethanol use.

Of course Honda will allow you to use E10 because the damage won't occur within the warranty term, any issues after than you'll be buying Homda replacement parts, more money to them.

Remember shell e10 is a mix of 91 ULP + 10% ethanol (of which 6% is water), the 94 ron comes from the octane boosting effect of ethanol.

The knock sensor may prevent pinging, but remember your ECU is still tuned for 95ron +

[chuboy]

Not necessarily. Honda specified a power steering hose that could fail under normal operating conditions. They are now paying dealers all over Australia money out of the company bank account in order to replace the components, even on vehicles that are well out of warranty.

If they say you can use E10, and you do, and it damages the car, then they have to replace your parts free of charge. Or at least, a decent lawyer could successfully argue that case.

The ps hose is another matter. the anti frothing agent is to prevent damage to the steering rack, a different part altogether.

Honda says you can use 95ron plus e10, not 94ron which is below the bare minnium fuel rating, e10 or not.

Top Gear drove a Prius at top speed through their racecourse and got a BMW M5 (I think) to follow behind it, matching pace.

The Prius used way more fuel than the BMW despite the BMW having a thirstier engine. Smaller engines have to work harder to acheive the same performance.

That is true. Saw that as well (was an M3) but I don't drive with a heavy foot (whereas the Prius was flooring it the whole time). Out of curiousity, what sort of fuel consumption do you get on your 06 euro?

[buddah51au]

Generally, a bigger engine does not have to be worked as hard as a smaller engine to achieve the same performance, therefore less fuel is used. I say generally as my FD1 civic Auto averaged 6.83L/100km over 60,000km, yet my CU2 Auto is averaging 7.07L/100km over 37,500km. That is only a difference of 0.24L/100km. Figure that one out, I can't.

Generally between 7.0 and 9.5 L/100km depending on the ratio of highway to city I've been doing (I usually reset the counter every tank).

[Neesmo31]

Just for reference, i just got back from a long trip to mackay and back.

Fueled up before i left (BP Ultimate) and went there and back on 1 tank. The fuel light turned on after i had done 780kms (just when i got home)

So it would be safe to say that for a full tank of ultimate i could get easily over 800kms to a tank!!!!

Is this normal for everyones Euro????

[buddah51au]

You should be able to do better than that, I have no trouble getting 900+km with my CU2 Auto

[Neesmo31]

I fueled up this morning back to full again. 53 litres. So 770kms to 53 litres. There was many spirited overtaking involved, and I spent a couple of days cruising around mackay traffic. All in all i think thats excellent for the Honda :)

Thats an average of 6.8L/100kms with traffic driving incorporated! I dont know what other people are getting but i think that is so good :)

Sure beats the patrol, it gets 500kms to 150L!!!!!!!!!!!!!!!!!!!!!!

[CU2 Euro 09]

I drove from Brisbane to Mackay on nearly one tank. 40 psi in the tyres. Had the fuel light on for 20kms or so before topping up. Had spare fuel just in case in a Jerry tank. Wanted to see how far I could get. Stuck to the speed limit the whole way. Not much overtaking and not much traffic. Had to add 10L and got there without the light coming back on.

Here's the rough figures: 980KMS, 70L, 7.14L\100kms. The trip computer was telling me I was doing about 6.5L\100KMS.

06 CL9 Mostly urban driving, I rarely use the freeway.

That seems a little high, I usually average 10.0 absolute tops for medium-lead foot urban driving. Perhaps you are trying to match V6 performance with an I4? ;)

Well I had a 2003 Laguna before this and I never took it past 4000rpm because I was too afraid something would go wrong with the engine due to the fact that every other bit of the car had developed a problem!

So I basically drive the same in the Euro out of habit and always use BP ultimate, but even when I try to be as frugal as possible (air con off, windows up, keeping it under 3k rpm etc), I can NEVER get it below 10l/100km with a mix of suburban and highway driving. If I go on the freeway and coast then it hovers around 9L/100km.

The thing about euro and drive by wire is that rpm is not a good indicator on how much fuel your car is drinking..... If the cr is more than 5 yo I might suggest anEFi system flush/clean.

And tr reset your eCU... That'd probably help

Cheers for the tip, couple of questions:

How much on average does an EFI system flush\clean cost? and,
I tried to reset the ECU recently, disconnected the negative terminal for 10 or so minutes. It cleared the fuel consumption figures but not the distance traveled in each of the trips, A and B, in the trip computer.....would that still be considered reset?

[Fredoops]

It's about $110 odd, And yes, that was a reset

[ryaan]

i have a cl9, all city driving. getting about 11-12l/100km. worst fuel consumption ever for this type of car im guessing...

[dee-y]

I get about 10 ish. Does anyone know how far the car can go from when the light comes on till it runs out of juice?

[euRo_noob]

I get about 10 ish. Does anyone know how far the car can go from when the light comes on till it runs out of juice?

Pretty hard to say.. It would depend on how you drive I suppose? Like how hard you step on the accelerator etc etc? For me, I can still get another 50-70km probably? Haven't actually tried it out myself to the point where the car doesn't run anymore lol.

[chuboy]

I find that car always has at least 6 or 7 litres of fuel left in when I fill up after the fuel light comes on. So I suppose driving averagely you could get up to 80 kms. Would be a good experiment, but only if you had a jerry can of fuel for when you did run out.

[Lazarus]

Just passed the half way mark @ 350km so better than before...weird

Guys ,

if your car is lowered with eibach springs does it effect fuel economy ? also if you change wheels from 17' to 18'

[Fredoops]

Guys ,

Yes, but how much difference depends on the setup, width/weight of rims etc etc etc

I remember someone said each kg gained on the wheels is the equivalent of 4 or 5 kg gained on the bodywork or something..

[chuboy]

Filled all the way up with Caltex 98 fuel. Then I did ~100km of <5 min 'cold engine' trips, ~230km of highway cruising then ~330km of reasonably lead-footed city driving.

I just filled up with 98 again from the same pump. According to the trip computer I drove 559.8km using 50.3L of fuel (which works out to be about 8.985 L/100km). The trip computer showed my fuel consumption as 8.7 L/100km. So the trip computer appears to be about 0.3 L/100km optimistic judging by other posts here as well.

EDIT: I got stock 16" wheels at 36psi (although they were about 31-32psi for half of this tank. I'm surprised how differently the car handles when you pump the tyres a little harder).

[[SDCTVE]]

I get about 10 ish. Does anyone know how far the car can go from when the light comes on till it runs out of juice?

according to the owners manual there's about 10L left when the reserve light comes on, so depends what you averaged for the first 55 liters.

I got 500K's (2003 manual luxury, done about 128,000kms) before the light came on, mostly urban driving using Caltex Vortex 95, with the occasional heavy foot on the pedal, but most of the time changing at about 3500 for the early gears and about 2500-3000 for the higher gears.

so out of 55 liters I got 500k's = 11L/100kms..... not bad, I'm gonna try BP ultimate next, shifting no higher then 3000 and hope to get 600k's before the fuel light comes on!

[MingZai]

11/100?? not bad??? thats horrible isn't it......

[[SDCTVE]]

11/100?? not bad??? thats horrible isn't it......

It's not that bad considering the amount of kms, almost due for a service and the occasionally hitting 5500-6000 rpm.

whats your fuel consumption like?

[MingZai]

i got like 440km..... worse then u... I think I hit VTEC too much....

[Musti]

Sorry if this has been mentioned before, but everyone should make an account on fuelly.com - it just makes it easier to track how much you've spent, distance travelled and all of that sort of stuff. And you can search for specific cars. It's free. (And I promise I'm not affiliated with them)

[euRo_noob]

I'm surprised I've been able to keep my car at 8.9L/100km for the past month and a bit. I do a lot of short trips (picking up brothers, groceries, driving to the city, friends house etc). I also do drive in peak hour/school hours quite a bit and once in a while, I'd get 10-25mins on the freeway. Guess the light footed driving is working. I do hit VTEC here and there but I try not to since my car is still fairly new.

[[SDCTVE]]

well I filled up on thursday, and I've just hit 300kms, and the fuel guage needle is sitting just over half a tank! I have been changing gears less then 3000rpm about 85% of the time, which is pretty good for me, I was a bit of a hard driver, I've calmed down heaps. this time i filled up premium 95 from 7-11 (previously a mobil) so i dont know where 7-11 is sourcing their fuel from now, but from memory 7-11 fuel was shit house! but im pretty pleased considering the last tank of fuel was caltex vortex 95, and at about 250kms my fuel guage was pretty much half way!

[MingZai]

hmmmm I've only hit VTEC once so far ever since my refuel... going to measure again once it hits the light.
BTW what do you mean my light footing? not stepping on the pedal yeah??
Too bad I have an INJEN CAI which makes me want to step down on it all the time..

[aaronng]

I used to drive around Eastern suburbs in Sydney and would hit redline going from 0 to the 90km/h limit once a day. Still got a fuel consumption of 10.5L/100km. Hitting vtec/redline once or twice a day doesn't drastically increase your fuel consumption because the time in which you are using full throttle is very short compared to the rest of the time when you are driving normally or idling in a traffic jam. I've also testing driving full throttle for 90 minutes on a race track, keeping the revs from 4000 up to 7000rpm and got about 27L/100km.

[[SDCTVE]]

so when does vtec actually engage in the k24???? I was under the impression that i-vtec technology is more gradual as vtec engages, kicks in earlier and you dont really notice or hear it as much.... i tried to search info on it but u can imagine how many results come up when i type the word 'vtec' in the search bar haha

[Fredoops]

6000 rpm

[MingZai]

^ thats right 6000 rpm. Well quick update... My fuel tank is 1/4 down and surprisingly it's already done 220 km :D .
I've hit VTEC once or twice and been driving it like a prius :)

Yeah, I mean just easing off the pedal a lot and not really stepping on it hard. And don't worry, I know how you feel.. I have a Takeda SRI and I've also disconnected my muffler (just for sound as it's still a bit quiet in the lower RPM's with a stock exhaust) and I'm always tempted to step on it harder just for the louder sounds.

Whoa, 27L/100km, that's crazy.. But I guess that's what you're gonna be getting since you're at a track.
On Saturday, after my friend gave me a run in his EP3R (me as the passenger), I gave him a run in my Euro just to feel the difference (but obviously, mine no where near as fast as his). We both ran our cars for about 10mins of VTEC'ing each down empty streets and I thought my fuel consumption would've went up but luckily it stayed.

If mods do affect fuel consumption, I just have a Takeda SRI plus the disconnected muffler. I also run on BP Ultimate.

I thought it was around 5800 but I guess it's 6000rpm, I'll try pay more attention next time lol.

Also, could anyone please explain to me the difference between i-VTEC and VTEC? People ask me and I don't know who to ask lol. (You could PM me if this is getting off-topic. Thanks.)

Just to throw another users experience into the mix. I have about 2000km on the clock and have averaged 7.8l/100km. This is a mixture of highway at 110km/h, freeway at 100km/h and around town in a ratio of around 50:40:10. Currently averaging 81km/h.

This is with some pretty spirited driving inbetween the highway clicks. I have had it as low as 6.5l/100km on just freeway driving stretches.

Cheers

Far, 7.8L/100km.. Saving heaps of money on fuel! I'm averaging like.. around 38km/h :\

[tron07]

my best FC... 5.1l/100km.... Pump petrol at Sutton Forrest Shell, reset and drove off, did it for around 90km distance doing 110km/h on cruise control on M5. photo taken in the 70km plus mark. Was trying to see if it drop to 5.0l/100km but hit traffic jam and slow to a crawl and FC went back up to 6.0l/100km before going smooth again.

ahh i wish the 03-05 euro had a proper trip computer :(

[chuboy]

I filled up with Caltex 95 for the first time last week. I have done a good 100kms so far on this tank to reach the same fuel tank level (driving style and conditions identical).

Trip computer agrees showing 9.1L/100km up from 8.4.

So there you have it.

[buddah51au]

In the 3 years I had my 08 CU2 Auto the average over 40,000km was 7.1, best recorded was 6.23. It will be interesting to see how the MY12 compares over time. I mostly used Vortex 95.

[adis]

average 8.3-8.4L per 100Km. Mixed driving, mixed road. CL9

Wow, i got the same car, driving harder compare to you (sounds to me anyway), and i get 630 before the light comes on... Why such a huge difference? hmm

[jbzonda]

Hey Guys, first post for me - just recently bought a 2006 Accord Euro CL9 with 97,000km on the clock. bought from a dealer with new tyres.
so far so good for fuel economy - better than i expected.
1. First Full fillup was Caltex Vortex 95 and got 640km when the reserve light comes on - then filled up, average 7.2lt/100km 70% Freeway 30% Urban
2. filled BP ultimate - improved economy again down to 6.8lt/100km so far with 540km and gauge is saying there is a little more than 1/3 of a tank left. so far so good! again same ratio freeway/urban.

on 1 run Monash Freeway and Eastlink - about 30km distance i managed to have it down to 5.2lt/100km on that stretch which is amazing!

[[SDCTVE]]

the car is now on 132xxx, service done, installed an Injen CAI, using BP Ultimate and I'm getting close to 600kms per tank.so averaging about 9.1L/100kms

pretty happy with that.

Just elaborating on my above post. So i ended up with 6.9ltr/100km which im very impressed with...fuel light came on at 736km and ran it to 769km and refuelled. Amazing numbers i must say - definitely a far cry compared to my previous car ('99 Mitsubishi Magna) which ran between 9.5-10ltr/100km.

[ryaan]

just refueled and calculated the fuel consumption.. turned out to be 10.7l/100km... all city driving, no highways, using caltex 95 57,xxxkms. pretty happy :D

[cris]

so the cl9 models before 06 dont have a fuel trip consuption reading is that right?

a 99 magna averaged 9.5-10? was it a v6? I had a V6 manual 97 magna, I used to average 13L/100kms but man that thing used to go pretty good :D

i had a 3.5 v6 Magna yeah they were great cars! i did have a few mods that may have helped the economy...i usually got 550-580km per tank most of the time
Dont forget too that most of my kms are 70% freeway, im sure around town its much worse.

[ricerockets]

Just did melbourne to adelaide about 720kms and no fuel light haha

[mugen_ctr]

hey guys, been driving the euro, having a hard time even getting figures like 10/100kms!!!! only mods to it is the short ram intake, is that the cause to the poor fuel usage?

Does this sound right though?

Been running bp98, half city use, half suburban use, no high way drive...

[ricerockets]

might just be your foot lol, ive got a cai and afc neo installed and i get around 650kms a tank for city/surburban driving

mind you ive done the throttle body coolant bypassing mod

see thats what i though, but than i look back on my and the way i drive is quite modest and light footed.... on my civic i get around 9.5/100kms, so realistically i should be getting around the same fuel consumption of atleast 9.5/100kms or less cause its a much newer car and the k24 is reowned for good fuel consumption... and much bigger engine

it really depends on the traffic condition as well.. some poeple here drive on free flowing traffic on highways and hence the good consumption..it really depends.. all i know is that the cl9 k24 is sh*t in the city..especially stop start traffic.. . its like a v6 consumption.. but its only a tiny i4

[jbzonda]

Question.

how far do you guys run your tank to? for example i ran mine down to the trip computer saying i had 26km left, ave 7.2lt/100km and roughly 730km to the tank. BUT when i filled it only gave me 55litres. so even though the trip computer says its close to empty, will the tank still have upto 80-100km of fuel left?

[mugen_ctr]

fair fair....didnt know k24 are crap for city drive.... ill have to try it on a free way an see how it goes, cheers :D

Yeah traffic could be a factor

Adelaide traffic is a lot more free flowing than melbourne and the likes

[azn_k3nt]

in melbourne stay away from monash, westgate and prinny hwy (caulfield to the city section) or else prepare for bad fuel consumption.

I get around 7.9-8.1lt/100km and only drive through peakhour once or twice a week, I rely heavily on Prinny hwy to give me good fuel consumption.

K24 is really bad on slow roads and streets is like the car is telling you WTF AM I DOING HERE!!! =="

maybe being angry for being in the heavy traffic is giving you a lead foot lol!
Nah i take the Monash too, im hovering around the 6.6-6.8lt/100km which has included today horrific run in bearly going 60km/h between eastlink and warrigul rd.

what petrol u using? i find BP Ultimate is the better of the 3 major Fuels.

[mugen_ctr]

Now im starting to hate it.... only managing 11-12 liters per 100kms daily driving >_<

This is getting ridiculous, im using more fuel than my civic....

either the Short ram intake is playing with the afr, this meaning needing a oem air box or either the o2 sensor is playing up...... any ideas guys?
