Fuel Consumption

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

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.

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

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.

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.

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

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?

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

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

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

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.

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.

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!

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.

My WRX would give me 13-14 L/100km when I used to stroke it. Much worse when on fire. But, man was it fun! I miss my WRX. I don't miss the sh*t interior.

I dont know what are you guys complaining about, My last car(CX7) was doing 15-17L/100km at the best!

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

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.

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.

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.

Flat tyres FTL :(
I hope you meant 38/36psi.....

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

Hmmmm..........Gladstone to Hervey Bay every 4 to 6 weeks ....... 6.4 - 6.6 every trip. Tyres 36PSI, Vortex 95.

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...

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!

I flog mine all the time and get 8's. You must have some really bad stop - start driving!

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.

2006 cl9 luxury,

uses 11.5 l/ 100km on the trip computer

i think this is way too heavy for a 4cyl....

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.

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 :(

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

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.

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 :)

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.

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.

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.

2006 CL9 Manual

I used to get 9-10L/100kms with city driving (normal traffic).

Ever since I worked this new job where it takes me 1 HOUR to travel 20kms, in mostly start/stop traffic, i've been getting 11L/100kms!

**** 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?)
tyres are pumped at 38/36
and i havent had a wheel alignment done in over a year.
everything else is stock.

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?

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.

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

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.


http://i388.photobucket.com/albums/o.../SydTrip09.jpg

http://i388.photobucket.com/albums/o...SydTrip092.jpg

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

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

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.

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.

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 want KM/L that's easy, as of my last fill 36,628kms / 2592.22Lts = 14.12997353 km/L. Is that good enough?

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

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.

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.

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

Sent from my custard cannon like Peter North.

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...

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.

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

Its safe to mix 95 with 98.
91 is a big no no from what I heard...

Ohh alright then, thanks a lot Fredoops!

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?)

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