There is an old thread about Euro consumption lurking around - but it would be good to have a thread showing figures for owners who accurately log consumption over the life of the car.

Post results here! I am really impressed with the figures I get - almost all city driving with lots of stop/start and plenty of WOT.

How about this format:

Model: 6mt
Mods that could impact consumption: wider tyres, rims
Kms: 19,500kms
Highway kms (steady 90kph+)-estimate %: 5%
Average Consumption over life of car: 10.26

***
Update - consumption is improving

Model: 6mt
Mods that could impact consumption: wider tyres, rims, filter
Kms: 30,000kms
Highway kms (steady 90kph+)-estimate %: 5%
Average Consumption over life of car: 10.07

Mods that could impact consumption: VAFCii, K&N Typhoon CAI, ZORST
Kms: 23,500kms
Highway kms (steady 100kph accurate)
Average Consumption over life of car: 9.23

Has anyone seen the latest Wheels magazine (April 05). They have a long term Euro which does mostly short trips - their fuel consumption for the last month was 14.1/100kms. :eek:

How on earth can you get 14.1? Even if I had a heavy right foot and bumper to bumper traffic every day I can't get close to that.

Well - i find that the Aircon makes fuel consumption particularly bad. I expected a modern car like the Euro to perform a bit better. It really drains power to the wheels in hot weather.

THe guy probably had a lead foot that month. Being stuck in traffic jams, maybe he idled a little too long! I have that Wheels issue. I don't remember them explaining why consumption was so high. I'll have to read it again.

The Wheel mag long term Euro they are testing is auto as well which wouldnt help matters on top of the short trips and most likely heavy footed driver with aircon on...who doesnt thrash a renter car when given a chance... :)

(plus they havent stated what type of fuel they are using i.e 95 ron caltex or 98 etc)

I fill about once every 1.5 weeks. I drove super enthusiastically for 2 days, heaps of full throttle up to redline, and got 11.5 L/100km. When driven normally with only 3 redlines a week, I get 9.2L/100km. This is in the city. Highway driving gets me 7.0-7.5 L/100km.

Can anyone give me an indication what type of fuel is best for the euro? As in Mobil, shell, BP or cartex? (of course 98oct fuel)?

I've got a fuel card for all... but hope its not mobil as Canberra have no mobil statioN!

I like Caltex Vortex 98. But every person has their own preference. If you are sticking to 98 octane, they are all good. Some people say Shell Optimax is not consistent, but I use that too.

VirIIx
06-07-2005, 05:18 PM
I love my optimax, but i don't mind using Caltex Vortex either.

Heard good things about BP Ultimate, but i didn't see it running as smoothly as optimax and i don't ever use Mobil. Only unleaded if it's mobil for other cars.

I've used it in 2 of my cars and the results have always been a negative experience.

aaronng
06-07-2005, 10:08 PM
I don't like BP Ultimate. Tried it a few times and it the car felt a bit sluggish. Might be psychological though....
Mobil Synergy 8000 is ok. Similar feel to Optimax. Hahahah, I sound like my butt is sensitive enough to detect changes from different fuels.

VirIIx
07-07-2005, 02:39 PM
I had real issues with Mobil. The car just chewed through it giving a really bad fuel economy impression and the car was choking while driving. It wasn't a really happy chappy. Then put back in some optimax and it felt alive again lol

V205
07-07-2005, 07:49 PM
Putting our butt dyno aside, I tend to choose the fuel that gives me most mileage. I remember when I was using leaded fuel, shell was giving me most mileage after many trials. I haven't done extensive testing on 98 octane fuels but shell is better than average from my research and other people's opinions from their own testing or research.

I still stand by my "Accidental" Testing between SHELL Optimax and BP Ultimate...

SHELL Optimax does give the extra power but the sludge build up in the engine is quite bad.. sort of..

BP Ultimate on the other hand cleans out the sludge that built up in my engine when I was using Optimax.... And it gives cleaner emissions too...

Like V205, at the end of the day, it's up to individual... I personally prefer a cleaner engine..

I think we should discuss what fuel is being used too. I only use ultimate which is a 98 RON. So maybe 95'ers are getting less / more?

aaronng
08-07-2005, 02:31 PM
It's all from what people hear and experience. The problem might not be caused by optimax alone, but we are quick to put the blame in it.

Example, my girlfriend's Astra has a sticky throttle butterfly after 3 years. Dealer says that it shouldn't happen if you're using premium fuel, but still happened to hers. For me, I'll alternate or something. Maybe fill every half tank with optimax to see if it feels ok.

Edit: I use only 98 octane.

That was a great write up by our north american friend.
Do they have different octane rating system?? how come they have 89, 91 Octane level, and yet still get all the performance and fuel efficiency??
Do they have diffenrent engine set-up to cope low octane fuel? :confused:

Yes, they do have different octane rating system.
From memory, their 91 octane is the same as our 98 octane or something. It's been a while, so I'm not sure if that's 100% correct. However, I'm 100% certain from memory that their 91 octane does not equal our 91 octane.

08-07-2005, 07:42 PM
I've never given other petrol a chance. Have always used BP Ultimate from the beginning.

Maybe I'll try the Optimax or the Vortex 98 since they have petrol discounts with supermarket receipts. worth a try I suppose.

aaronng
08-07-2005, 09:44 PM
Our octane rating is the research octane number (RON). The US uses the formula (RON+MON)/2, where MON is the motor octane number which is determined by actually running the petrol in an engine and it is a lower value than RON. So for the same sample of petrol, our system would give a higher number than in the US.

I got my first reading after my first refuel [to the top] with a brand new auto luxury.
Oi - about 350Ks out of a full BP Ultimate tank before the low fuel light came on; that equates to about 1.4l per 10Ks if this happens @ 10 litres left.

Usage: A good few short trips in the city, trying the engine out etc, plus the relatively cold weather - all in all that probably doesn't make for very good fuel economy.

After this I didn't fill the car completely up as I wasn't happy with the fuel price, so this throws followup monitoring out a bit.

That sounds extremely high even for a brand new car.
Cold weather should actually improve the fuel consumption, not make it worse.
I don't think I ever got mine to go above 10L/100km, even when pushing the car very hard constantly, which I was very pleasantly surprised about.

The first fuelup is always high, because the dealer doesn't fill it to the top for you. My first refill was 15L/100km.

coladuna, you driving an auto or manual? I've not made ANY effort whatsoevery to conserve fuel, so if I tried I'm thinking I should be able to do a lot better. Well, I'll record it from next time I fill her up completely and see how it goes. Should also be able to go for a longer drive next weekend so that might be good for it.

My measurement was from resetting the trip counter on filling it to the top myself. I just confirmed with my manual page 87 that it comes on when remaining fuels is LT 10.0 l [or 2.64 US gal, 2.20 Imp gal]. So I actually managed 1.4L/10km for my spirited stop go driving...

You driving the auto or manual? I get below 10L/100km ever since I filled up my own full tank from brand new. I drive the manual, and I find less than 1/2 throttle is enough for everyday. Each week I sprint up to 1st gear redline about 2-3 times and everyday I do a full throttle run up to the speed limit (80km/h) in 2nd gear without hitting redline in 1st.

Remember to check your tyre pressures (32-34psi) and use 98 octane for added distance (Euro's engine will advance the timing on 98 octane so you get added range)

I'm driving manual, but I even went to Mt Tambourine and absolutely flogged it through the mountain climb and twisties and it still didn't go over 10L/100km.
Probably did around 400km with that tank and out of that, 200km would've been drive through the mountain while the rest is highway.

Coladuna - the Euro's got a 65 liter tank. 10L/100km should last you 650Ks, or 550Ks if you want to count it to the reserve light instead.

Or are you saying that you put 40 litres into it to get it to full after you had done 400Kms from your last fill to top? If so, what you're saying adds up then.

Yea, I'm saying that I put in like $40 bux worth of petrol and I did calculation to come to a fuel consumption of less than 10L/100km.
The most I went with a single tank of petrol was around 650km when the fuel warning light came on. did another 20km or so and filled her up. My prediction is that you can have a range of up to 750km if you drive conservatively and around 600-650km in normal conditions.

I think it must be the frequent short trips, stop & go traffic combined with wanting to try the engine that did it in for me. I'm sure FE will improve remarkably when going on a _real_ drive.

That must be it. Each of my trips are usually at least 15km so the engine has a plenty of time to warm up.
I'm actually very surprised that the difference in fuel consumption isn't a lot even when I drive really conservatively as opposed to driving really hard.
If I drive really hard, I usually get around 9-9.5L/100km and if I drive really conservatively, I get around 7.5-8L/100km.

I'm getting crappy figures with just normal city driving.
Around 13Km/l (around 190km's on 25 litres of petrol).
This is on BP Ultimate fuel. I'm hoping this is just becuase the engine is still new, around 2.5K kilometres.

New engines will burn more fuel, it's normal during the breaking in of the car... I won't worry about it too much...

EA13, cool thought so... it all adds up. Any chance it is running richer than normal too? When I got my GSXR600 04 last December the fuel consumption was really not good at all for the first 1000Ks, but it improved a lot after first service and on subsequent use (especially after a Phillip Island school day).

Yes, nowadays, modern cars run rich from factory, you'll be shocked how rich the Euro runs from Factory, when I installed the VAFCii, I had it cut heaps and it was still running rich, I had a look at euro77's VAFCii settings too (Tuned at the same place), his fuel was cut a fair bit too....

Aratahu
11-07-2005, 09:22 PM
EA13: Interesting, thanks! In the 600 shootout of 2004 in AMCN [I think], my bike lost out to the competition because it "running rich from factory" deprived it of some top end power. On my first service, my bike mechanic said he'd set it up to go leaner. I think it did some good for performance and overall responsiveness.

Could someone more technical than me explain why they're running rich at the beginning? Is it to preserve the engine when being broken in? Difference in clima from Japan?? I assume it will be tuned to go leaner on first service.. (?)

I looked at this a while ago when Euro77 was getting his engine tuned. Became interested in the idea - for a few minutes anyway.

Excess fuel provides cooling as it evaporates to protect the engine.

There is a good discussion on this forum - for science geeks.

Check the other threads for tyre pressures.

It seems most people have it at from 32F/30R up to 40F/38R.

Most car manufacturers will set low fuel light at approx 10 litres left in tank. I wouldn't trust it totally, just fill it up when the light comes on.

Also, there is losts of dirt, crap build-up at the bottom of the fuel tank so not a good idea to run your car dry. You just don't know what rubbish gets injected into your carbie/engine.

Hi, i just bought my car about 2months ago. Its done about 2600km now. And i notice that it does about 500km or so (usually less) every time i fill it to full and let it get to empty. Usually when its @ empty theres about 10L left. I dunno it seems as though my car does alot more fuel that everyone else. I drive to uni and stuff so road speeds change from 60 to 80 alot. no freeways/highways.

I use premium fuel (vortex 95) and also never rev the car at all...so anyone know why? lol

Awww.. you don't give your baby 98 octane? My car prefers wine over beer (no offence to beer-drinkers!). Use light throttle applications when possible, and change at 2500rpm, and you'll get 9L/100km in no time. Makes the drive boring though. Hehe.

I just filled up at a Shell station instead of my usual Caltex. The difference in full tank is 4 litres due to the pump stopping earlier. Quite a big difference!

I have had my Euro for 14 months and avg 10.74 Kms/L (9.31L/100Kms). So on a tank of 65 litres, I would get about 700Kms per tank. My warning light comes on at around 550/580Kms and is consistent with about 10L left in tank.

During the early months I was getting below spec mileage. After about four months, the economy became more consistent. I now do better than spec and very rarely worst than 9L/100Kms.

I believe your mileage figures will improve once your car is "run-in" and also when you are used to the gearing ratios (if you have a manual). I notice the economy goes "a fair bit" when my wife drives the car (she has a lead foot) - haha.

Other than that, check your tyre pressures and do a bit of country driving to see if more cruising makes a difference

Yeah i was worried. THought maybe my car had something wrong with it. I dont use the triptronic (manual) feature because i dun wanna do somethin stupid and screw it up. I try to keep the revs under 2500 alot...but yeah it does get pretty boring when driving. I dunno would the fact that the oil wasnt changed at the 1000km service be a problem? i dun think they changed the oil...not sure lol. I also wanted to know...coz i use Vortex Premium (Oct. 95)...but i think my car does slightly better in fuel when i use Vortex Premimium 98....whats the difference?? what does this number represent?

if i do no hard revving i get about 570km/tank. this is mainly city driving and start/stops on the way to both work and uni and morning traffic...keeping my speed at 95-100 on the highway.
if i give it some on the highway and if i feel the need for speed, i get about 500 per tank....500-510...about there

I have never really paid to much attention to this topic before but since I changed my oil type to 0w-20 instead of conserving petrol which what its suppose to do, seems like it chewing it up :( not happy Perhaps the oil is to thin I still do not know I here so many comments but don't know who to believe.

If it continues maybe will change to Motul either 5w-40 or 0w40 that may do the car some good.

It is hard to follow your figures as I don't know when you say "to a tank" whether it is to the low light or to empty. Those figures are terrible if it is to empty.

how do u guys know about ur fuel consumption?

Rough and Ready method. Fill her up, reset trip meter, drive, fill her up again and record distance and fuel used then do the maths (650 k's and 50 litres = 13 km/litre = 7.69 litres per 100 km = 36.7 mpg. A one off tank measure can result in significant variation due to just how full you get it each time. (My tank to tank figures vary from 11.7 km/l to 13.8 km/l, but average at 12.9/ km/l. Driving enthusiam also impacts on consumption!)

The more accurate method is to keep a running record over a number of tanks and record starting k's finish k's and all fuel put in. If you are really keen, keep a spreadsheet. If you have to keep records for leases or the like you alread have the info that you need.

it seems impossible to get 9L/100km in city areas..like no long distance driving i mean....mine does about 11L/100km i think. When measuring does it matter if you decide to refuel every time you get to half way? coz i feel that first 200kms or so is good with fuel then it gets to be more....or maybe i just rev it a bit...i dont really...on ocassions i go to 3000RPM - 4000RPM...i try not to.

In regards to not fueling up when its almost empty...i can see what you mean when you say dirt builds up at the bottom...so its good to fuel up when you have around 10L remaining...but doesnt the petrol get sucked out of the tank from the bottom anyways?

If you're doing 100% stop start traffic (i.e. traffic jams and traffic lights), and drive an auto, then it will be difficult to get 9L/100km. For me, I shift at 3000rpm in 1st, 2500rpm in 2nd, 2000rpm in 3rd to 5th. It's a very low shift point, because it's just too busy here to accelerate quick. But I drive this way when I am in the city/suburbs, and when I get out to less populated areas, I can give it a full throttle to redline about once every day or 2 days and still get 9.5L/100km. The car is very efficient if you apply light throttle to maintain speed, because it has EGR to reduce fuel consumption. And when going downhill, leave the car in gear and don't press the accelerator. This closes the throttle while keeping the engine spinning.

way2quik
21-08-2005, 06:16 PM
yeah but i dont use the triptronic feature. So i dont know when it shifts. But i just ALWAYS try not to go over 2500RPM now. Well this is what im goinna do from now on. That will surely reduce fuel right? what is EGR? i was also wondering like say you drive at 80KM/hr and a traffic light comes up so you gotta go to zero. Is it better to just apply breaks and let the automatic downshift to every gear until zero stop OR is it better to put it on neutral and let it slow down to zero without changing gears?
I know its weird to do this on an auto but i thought it would be better.

The figures I have posted on the previous page are based on a 55 k commute each way, of which approx 30k are running on the freeway, against the traffic, i.e. basically 100 kph constant speed. Another 10 k is as at 80kph with a few stops and the balance is typical suburban. Manual transmission helps.

My figures are more realistic, since I live in the Eastern Suburbs of Sydney, drive through the city (with the damn traffic jams once in a while), go through the tunnel and out at Willoughby, up past Chatswood to the Northern suburbs. So my driving is city driving with 50 and 60 speed limits, while the Tunnel and the short stretch after that to Willoughby is limited to 80km/h. I'd claim that my driving is 70% city and 30% on the tunnel/freeway, without exceeding 80km/h (unless I want to lose my license).

EGR is where part of the exhaust gas is recirculated into the intake, so you have some exhaust gas (not combustible) and some fresh air. Since fuel is only needed to be injected based on the amount of fresh air, the exhaust gas will become a filler, and thus you use less petrol, only the fraction required for the fresh air. The EGR system only activates at light throttle with low load. So it is easier to drive with it with a manual rather than an auto. But basically, if you keep your foot only lightly on the accelerator so you can maintain speed or even accelerate slowly, you'll save lots of fuel. This is probably the reason why the Euro is able to return fuel consumption figures similar to the official figures, while for other cars they usually return an extra 1L/100km higher in real life.

When you are slowing down, DON'T put it to neutral. Even a driving school will tell you that. It's for safety, in case you need to accelerate to avoid an accident. But also, when slowing down and leaving it in gear, the ECU will shut the injectors, letting the engine spin using the momentum of your car, thus saving A LOT of fuel.

Just use your brakes normally. Let the auto transmission downshift itself, in D. There is no point is purposely engaging a low gear to engine brake. You'll just wear your transmission a bit more, and saving the brakes is not really worth the potential auto gearbox wear.

A lot of the fuel consumption figures are amazing. Most likely wouldn't be able to pull it off with an AT. But then again, it's possible to get good fuel economy just by taking it easy. IE, don't plant your accelerator too heavily at the lights, taking your foot off the accelerator earlier when you see red light ahead, etc.

Yeah, here are my top tips to save fuel:
1) If you don't need to accelerate quickly off at a traffic lights, use LIGHT throttle and shift at 3000rpm in 1st, 2500 in 2nd, 2000 in 3rd, 4th and fifth. Don't use MEDIUM or HEAVY throttle and shift at 3000rpm in 1st, as that is just a waste of fuel It is not the rpm that consumes petrol, but the amount of throttle you give.

2) When you are going downhill, even a gentle down slope, use 5th gear (or 6th if it is downhill at 80km/h and above) and release the throttle. This closes the injectors, while still letting your speed stay roughly at that point.

3) When slowing down, DON'T shift to neutral or press the clutch. This not only takes away your opportunity to accelerate in an emergency, but also forces your engine to spray the injectors to maintain idle speed rather than fully close and rely on momentum to spin yoru engine.

4) When maintaining speed, use the ideal gear to keep at 2000-2500rpm with VERY light throttle. This activates the Exhaust Gas Recirculation (EGR) system and saves you fuel.

5) Other tips recommended such as driving closely behind another vehicle to cut through the wind and using neutral downhill do not save enough fuel to offset the additional risks you put yourself in. So it's not recommended to do those.

Oh yeah, regarding tip #1, notice the revs are very low in 3rd, 4th and 5th gears? It's between 1500-2000rpm there, so you must not press the accelerator too hard! Otherwise you'll lug the engine. With light throttle, the car will accelerate, but with heavier you'll feel the engine vibrating more as there is more engine load but not enough revs.

way2quik
22-08-2005, 02:41 PM
But usually when i slow down to zero from 80 at traffic...i watch the rev meter...and lets say it stays at 1100 rpm...at 60 when i slow down to lets say 40 the revs will go up to 1300rpm or something...then go back down...and so forth when you slow down even more..so from that i see that its downshifting constantly till u hit zero.

Thanks alot aaronng, i understand what your saying now...i usually do accelerate very lightly especially at the start when u leave at a green light. sometimes you can accidently push a lil more force and the car just moves of really fast. I always avoid that.

You can learn a lot about how to get good fuel economy by watching how GOOD heavy truck drivers drive.

Get off the power early when approacing red lights - try not to have to stop

Light application of power before the you start going up hills (on the approaching flat) - as distinct from waiting until you have started slowing down and then giving it extra throttle to get back up to speed.

Back off at the top of the hill, not when you have allready gained extra speed.

Change lanes when approaching a slower vehicle instead of getting behind the vehicle, slowing down, changing lanes and then having to accelerate.

Drive at a constant speed (when traffic conditions allow) instead of gradually speeding up, realising that you are going faster than you have intended, slowing down, and then repeating the cycle.

wow thanks for the info, looks like i gotta improve my driving by a fair bit. Its sometimes hard to accelerate slowly so it doesnt just move fast (giving that jerky movement -->which i think is what u call throttle)...but i gotta be real light with it.

I drove just then and accelerated very slowly...like not going past 2500rpm...its hard not to go over...but im gettin use to it...

I think my post at the bottom of page 7 of this thread covers what you are asking.

In summary, assuming that you filled you car to the same level this time and also last time the calculation would be as follows:

Distance travelled 517km, fuel used 48.88 litres. 517/48.88 = 10.58 k/l. To convert k/l to litre per 100/km = 100/10.58 = 9.45 l/100 km.

As per my earlier comment, this calc is only valid if you have filled up to the same level on both occasions. A one litre difference in the fills results in a difference of about 0.2 l/100km in the calcs.

aaronng
23-08-2005, 02:52 PM
You need to fill up to full tank once. Drive until the next time you need to refill and go back to that same station. If possible the same pump.

I've tried 2 stations, 1 shell and 1 caltex, and the difference in filling can be up to 5 litres. I have to keep pressing the pump trigger at shell station until it fills to the top where I can see that petrol comes out of the 1-way flap and then slowly flow back in. At the Caltex the pump only stops when it is filled all the way out of the 1-way flap and the petrol flows back in slowly.

So in my case, the caltex station fills more than the shell station that I use by up to 5 litres.

JDM Euro Wagon 24T 149kw/5AT

Car has factory trip computer that records fuel consumption and journals it to the dates between fills, it gives you instantaneous and average fuel consumption at any one time and distance left in the tank.
First tank of fuel the car said it had 660kms in the tank. Travelled 560kms the average fuel consumption was 11.5km/L and the car said there was just over 100kms left to go. This was on 91 octane (straight off the dealers floor).

Refilled with 98, same driving style and fuel consumption is way down at 9.5km/L. This is no A/C driving.

24-08-2005, 11:19 PM
I wouldn't trust what the trip computer says 100%.
The most accurate way is to fill it up, reset your tripmeter and then see how much petrol you have to put in to fill it up the next time.
Got 8.9L/100km from my last tank. I used to get around 8.5L/100km and even less sometimes, but it's been creeping up lately. It must be because the car's due for a service in the next 1000km or so.

Fuel sure is getting expensive. I just did a couple of thousand Ks and worst case being a full 58 litres @ 1.40-something gives me about $80 for a fill up. It is good that there is a full 12 litres or something like that once the reserve light comes on..

A tip - always ask for the receipt and note down your total odo on each. you can then put the data into a spreadsheet and do the calcs when convenient - the difference between last refill's odo will become the mileage. Until then, the compartment just under the armrest serves nicely for those receipts and a pen to annote them.

It will also become a history of your driving plus also if you should ever have a petrol related problem, you have your bases covered. I also like to keep an additional note field of my driving style with that.

Just wanted to boast my new fuel consumption record.
I cannot believe how I got it this low because I didn't drive like a granny at all.
I'd say it was about 60% highway although it wasn't all smooth cruising because of morning rush hour traffic. Also, I happened to have quite a few spirited driving sessions with this tank of petrol too.
I managed 7.48L/100km (Did about 169km with around 12.5L of BP Ultimate. can't remember exact distance now).
This was with 36psi at the front and 34psi at the rear. (measured when cold)
I'm thinking that changing to fully synthetic engine oil has helped also.
I still cannot believe this kind of consumption. I used to hover around 8L/100km even when most of the journey was highway crusing.

My First post in this forum :)

Many people say that BP Ultimate is better than Vortex or Optimax. I dont know about Vortex, but certainly Ultimate is better than Optimax. I use Ultimate, and I got a friend who use Optimax. After 3000kms, I notice the difference between those fuels on the exhaust. My friend who uses Optimax got a slightly dirtier exhaust than mine. It is caused by the residue left behind by the fuel after being consumed by the engine. My friend who studied mechanical engineering said that dirtier exhaust is caused by less good fuel (sorry about the english, but I dont want to state that one fuel is better than the other). I'm not sure whether it is true or not, but the logic makes sense to me. Please correct me if I'm wrong :)

Now about the fuel consumption. My Euro is 2005 with AT. I can say my Euro got a very bad fuel consumption. I normally drive at CBD area, so I get roughly about 350kms with 50L of BP Ultimate. Last 2 week, I went to Ecucha at NSW from Melbourne. Return trip takes about 500+ kms (we were lost on the way to Ecucha), and it only consumes less than half tank, with 4 people in my car including me and stuff like my OEM suspension in the trunk.

It sounds weird, but its true. I dont know why myself. The same thing happened to my civic. From Melbourne to Wilson Prompt, 600+km return, it only took around 35L of fuel (forgot what fuel I used).

aaronng
27-09-2005, 11:58 PM
ngupil, since you are able to get good fuel consumption when driving on the highway and your CBD driving only gives 350km with 50L, then it is because of start-stop traffice plus the fact that many auto drivers tend to press the accelerator past 1/2 throttle to accelerate from stop. I spoke to a few auto Euro owners and they get only 400km out of the tank (before the light comes on, so about 50L or maybe 55L).

It is a heavy foot that really increases fuel consumption. As with the manual, I only need 1/4 throttle in 1st gear and even less than 1/4 throttle in 2nd gear onwards and I get 560km out of 50L driving in Sydney and crossing the tunnel. I don't go onto highways into the countryside. I have driven to canberra, and I could make the journey there and back without refueling!

I thought that my consumption is very bad, but I guess if you say other AT Euro owners only got 400km out of the tank, then mine is pretty normal.

What is heavy foot? I normally drive rarely exceeding 3000rpm, and I accelerate slowly. Even old cars from the 70s or 80s sometimes accelerate much faster than I do at the red lights. I also put my gear into neutral way before I stop, to save fuel. I'm not sure whether or not it saves my fuel.

Well for starters - don't put your auto in netural at lights to save fuel. If anything the car will use more fuel and just places more wear on the transmission engaging and disengaging drive all the time.

If you are getting 400kms to the light then it isn't great consumption but it isn't ridiculous either. It equates to about 12.5 litres per 100kms. Nothing great but (and I haven't got close to that in the manual) but still doesn't seem too bad for all Melbourne city driving in an auto.

Are you using 98 ron? When was the last time your air filter was replaced or at least junk removed?

Yes, my friend drives Euro as well, not one, but plenty of them!!. In melbourne, I see as many Euros as Commodores :(
yeah, I met up with 3 other auto Euro owners. They had similar fuel consumption. Another manual owner had similar consumption as mine.

I find that the rpm alone increases fuel consumption by a bit. But the amount of accelerator that you press does increase consumption by a lot. So to me, heavy foot = press a lot of accelerator. I only press about 1/4 of the accelerator when driving normally. That's how I get the low fuel consumption. But yeah, even the 2.2 auto Camry (older model by 2 generations) is faster than I am off the lights. Oh, and don't put to neutral before you stop. Because it doesn't save fuel. If you leave it in D and don't press the accelerator, then it will save fuel because the fuel injectors will stop and momentum will pull the engine to keep it running.

At the traffic lights once, there were 4 Euros including mine.... I don't even see that many commodores at the traffic lights at once! Hehe. Over here, the Euro drivers are mostly over 50 with white hair...

Ok .. I'll try your and yflin's recommendation, and see how the fuel consumption goes. It drives me mad looking at the prices whenever I drive past a petrol station, or when I'm smoking at my balcony, because there is a petrol station opposite my house =(

Off-topic comment ... are you serious that the Euro drivers are mostly over 50 with white hair??? Even my age is not half of theirs. I should set up a poll and see the result :D

Just forcomparison,
3 weeks ago I did 510KM with 52L of fuel.
and i only used Shell Premium unleaded RON95. (I cant find shell optimax)
and yes i tried to drive like a granny.

and using same fuel Now i have done 503km and about little bit less than 1/4 Fuel left in the car. im expecting to do 520KM this time before I fill up another ~52L

how some people here managed like 8L/100KM :confused: :confused:

I'm doing an experiment at the moment with Shell 95 fuel. and I did 320km's for half a tank, 90% city driving but driving like a granny. The 2nd half of the tank, I drove a lil harder 1 day cause I seemed to come across slow asses in the right lane and got the shits :). I'll let you know how many km's I get at the end.

My Fuel Consumption update: (2003 6sp MT ODO 34000km)
I've changed to Caltex gold (98RON) for a few months now, I can get 400km when the indicator pointing at halfway mark. 700km when warning light goes on. This including about 250km of highway. Only about 5% peak hour traffic jam. (Average about 7.9L/100km, or 12.6km/L) :D

I guess by turning off A/C 80% of the time in winter months helps with fuel consumption figures.

I guess I do more highway trips than any of you, but I redline my car all the time. lol
Probably like 3-4 times in each of my short 20km trip.
Even on highway, I don't sit on 100km/h with cruise control on. Always on the throttle to overtake cars etc...
Just waiting to see if this kind of consumption will be repeated again.

Because the fuel savings only happen when you engage the fuel-saving features of the Euro's engine. I personally have gotten the same mileage as the 1.8L auto Astra while driving in Sydney (all travel within a 30km range, from the Eastern Suburbs up to Frenchs Forest).

BTW, the 7L/100km is the figure for highway consumption. 9.1 or 9.2 is the official number from the EPA (am I getting the right governing body for fuel consumption?)

I get 9.5-9.8L/100km for that 30km range of travel and 7L/100km for 80% highway and 20% city mix.

Basically to save fuel:
1) Wse light throttle. Very light openings under low loads use the exhaust gas recirculation system.
2) when slowing down, leave it in gear and don't touch the accelerator. The injectors stop.
3) The less throttle you use for normal driving, the more fuel you save.

Do you get that information from the sticker on the windscreen at the dealership? If you do, then it is the most inaccurate measurement that you can ever get. They get that figure based on the average result that they get when testing it on the machine. It can be very inaccurate because it discounts the factor of wind, road condition (elevation, surface condition) in which can be deterimental in measuring the fuel consumption

The car is as fuel efficient as you drive it. Heck, I've driven a 1.3L car and gotten 13L/100km out of it, same for both city and highway driving! The reason being in the city it needed 5000rpm to accelerate and at 110km/h, it's sitting at 4000rpm!

The Euro's engine is above average in fuel consumption, ONLY IF you make use of the fuel saving features. Look at the Mazda6. It's about the same weight as the Euro, but it's smaller engine uses more petrol.

Usually what I do with the published fuel consumption numbers is add 1L/100km to it. And that would be closer to real life.

I have found the Euro to be one of the most fuel efficient cars i've driven for it's size. It's more efficient then a lot of my friend's smaller civic's and corolla's. Of course it won't beat a Toyota Echo.. but an Echo wouldn't beat a Euro in any other respect ;)

It all depends on the driver, I can vouch that i'm not the most efficient person when it comes to saving fuel, but I still pull an average of 500km, and fuel up 55L each week. And this is peak city traffic driving, and zipping around the city and suburbs during the day and night for work and personal. Aircon is always on, and I have my windows/sunroof down sometimes (for those who wanna get into drag effects about fuel :p)

That's because you don't brake as much when compared to city driving. The engine consumes more fuel when there is load placed on the engine.

I got a very crappy reading for the first time ever. 10.7L/100km.

I think much of it is to do with the fact that not all petrol bowsers fill up to the same point. This would cloud the figure a lot more I suppose when I fill up after covering only a short distance. If not, I don't see how I can make sense of such a huge difference considering that my driving pattern and the roads i travel on hasn't changed at all.

Do you guys in Canberra and Brisbane have Caltex Vortex Gold with 98 Ron Octane?
In Victoria I am only seen Caltex Vortex Gold 96 Ron Octane!



As for whether to use BP Ultimate 98, Shell Premium 95, Shell Optimax 98, Mobil Synergy 8000 98, Caltex Vortex 96 (Vic)..... well the thing is your car's ECU is best suited to the type of OCTANE that the car was tuned for.



Since a higher 98 Octane level fuel actually has lower volatility, which means its harder to burn despite having more potential energy, if the car's Ignition Timing is more conservative than the 98 Octane then your car will actually run richer and hence lose efficiency. Not to mention that 98 is more exxy than 95!


I am still deciding which fuel to use but with a lowly 7000rpm redline only (for a honda neway!) and a biggish, torquish 2.4L engine I would probably stick to lower end 95-96 premium for now.


Only thing I know is I would not use Shell Optimax however, it has very high sulphur content, it will affect the metal inside the engine, run dirtier, smells like bad egg, etc.


But if I will tune the crap out of the car with ECU, prob use Mobil 8000 Synergy > Optimax > BP Ultimate as most tuners don't recommend BP Ultimate as its susceptible to knock.. :(

You guys need to remember that the Euro's electronics 'learn' how you tend to drive the car & make it respond to your driving style. If you tend to give it a bootfull off the line all the time well that's how the car will respond. If you drive sedately, the electronics will adjust the throttle response & in the Auto , gear changes, to react like that all the time. The car will adjust to your inputs if it notices a change. But what it really means is that if you tend to run the traffic light grand prix everyday you WILL use more fuel because the car thinks you want it to respond that way all the time. It is far more complicated than I have just described but essentally that's what happens. :wave:

Drive the car sedately & the car will learn your driving style. It won't take long, but if you don't put the gas pedal to the floor, you will find that the throttle won't make the car leap off the line. A number of people have made mention in various threads about how sensative the throttle can be off the line. It's because the car thinks that you want it to be.
If you drive the car sedately the car will use less fuel, makes sense really when you think about it.

In theory the answer would be yes. The car reacts to changes in the way you drive it fairly quickly, so if you have been 'grannying' around town & all of a sudden you wanted to get stuck in, it would take a couple of changes before the car reacts differently. The changes we are talking about are only small. Things like the throttle response & the way the engine produces the power & in the auto, the way the box changes gear. All good stuff. :honda:

I pulled out the nozzle and saw that the petrol was not going down past the flap so it must have been full to the brim! So I got 8.7L /100km with aggressive city driving and this is the first time in my 13000km of driving the Euro where I have come upon such a low fuel consumption for such aggressive driving!

To add to my previous posting about the Liberty - have been driving a bit further now since the ECU reset which was done at the last oil change 600kms ago. The trip computer has settled on 8.6L/100km of 10% highway and 90% city roughly. So it sounds like the Liberty and Euro are very similar in this respect.

It should work for older cars where the injectors were not as efficient. But for newer cars, I don't think it would give as large a benefit when compared to older cars. At least it sounds more plausible than magnets in the fuel line or metal fins in the intake. However, I don't like the idea of preheating my fuel to 80ºC before spraying it in. I'm sure it would be ok since the fuel would cool down after spraying.

Only 1 thing though, they don't make it for the Euro (nor for any Honda). No Hondas in the upcoming vehicle list either.

To add to my previous posting about the Liberty - have been driving a bit further now since the ECU reset which was done at the last oil change 600kms ago. The trip computer has settled on 8.6L/100km of 10% highway and 90% city roughly. So it sounds like the Liberty and Euro are very similar in this respect.
My Euro is due for her service next month too. Hope that fuel consumption will improve when I switch from mineral oil over to synthetic.

Hi everyone :wave:

I just filled my brand new Auto Euro and got 9.8l/100klm from very spirited driving with about 10% highway.
I say "spirited" because I wanted to feel what this Vtec thing was that I've been reading about for so many years.
To say I was impressed is an understatement. I loved it so much I couldn't keep the needle away from it (the tacho needle that is) :D

My 1.8l auto astra got regular 10 - 12 l/100klm and it didn't get driven as hard as what I drove the Euro

I'm very impressed with the fuel usage :thumbsup:


P.S. This is the "right" way to break my car in isn't it? (I mean driving it like I stole it!)

Hi msnealo! You new on this forums? Welcome!

I broke in my car by giving the engine load. No babying at all. But of course, I let the engine warm up for 1 minute before driving off and then kept below 3000rpm without lugging the engine until the temperature needle showed that the was warmed up.

My gf has the 1.8L astra auto too! I was driving it for 2 years before I got my Euro. Same observations there!

It should work for older cars where the injectors were not as efficient. But for newer cars, I don't think it would give as large a benefit when compared to older cars. At least it sounds more plausible than magnets in the fuel line or metal fins in the intake. However, I don't like the idea of preheating my fuel to 80ºC before spraying it in. I'm sure it would be ok since the fuel would cool down after spraying.

Only 1 thing though, they don't make it for the Euro (nor for any Honda). No Hondas in the upcoming vehicle list either.

Hey, thanks mate, I wasn't looking carefully. Didn't know its not for Honda.

I keep a record of all fuel consumption. My Accord is the 2005 euro manual. On the last 8 fills the average is 7.64 based on shut off at the first click on the bowser. I pretty much exclusively use BP Premium (98 octane). The car has just over 8,000km and our best consumption is 6.44 by my, competitive,wife. These figures reflect country driving at around 70kph to 100kph on mostly light traffic roads in addition I would say 50% of the kms are on the expressway at an indicated 120kph for at least 1 hour to 1.25 hours. Yes I know it is ideal driving and I do see 6000rpm regularly. I am very happy with this as I have performance( Macquarie pass) as well as economy. My worst consumption figure is 8.27 Litres/100kms. :D

It is so hard to judge if this is good consumption.

Let's set some workable standard here. I have found the only practical way to judge fuel consumption is to fill to the first "click" write it down and the litres taken, ensuring you have 4 digits, delete the decimal point and divide by the number of kms travelled, e.g on 11/3/2006 I took 47.86 litres after driving 603 kms that gives me 7.94 litres per 100 kms.THEN take an average of, say 4 fill ups. That figure I used as an example is about average and is mostly at an actual (GPS configured) 115kmh (indicated on speedo 120kmh) for 75% of the time. I am not complaining :)

For those who want to explain all this to your grandparent in MPG then use the following formula. KMs divided by litres multiplied by 2.825 = MPG. I hope all this will generate some more realistic figures for this thread -- fascinating!!

Also, comment from other Auto Euro owners on city fuel consumption. Obviously the Auto is going to be worse, particularly in stop-go traffic but I have had figures for a tankful of up to 15l/100km. Since the first service this appears to have improved, and I know the car is still running in so things may improve slightly but OMG in traffic this car is a joke, may as well have a big aussie six! On the highway it is excellent. Drove 500km round trip when I first got the car and averaged 7l/100km which was fantastic. It's just like owning a car that has multi personality disorder I tell you.

I can appreciate the need for an auto in city driving so I am glad that I still have two legs and an open road down here. 15 L per 100 is not good so I sympathise with your plight. As you say on the open road it is a very different car. I suggest you wait for at least 14,000kms as I have found my manual Euro became much more flexible at this distance. The engine has become more, umm, creamy and very flexible. I often mooch along in 6th at 2,000 on undulating roads, which is about 80kmh or so.

When in the city, don't use 1/2-full throttle for take off. Use instead 1/4 throttle. You might accelerate only slightly slower (in my case, slower than a camry 2.2L auto) but you will save fuel and get 11.5-12L/100km. In the end, you'll be stopping at the next traffic light anyway.

haha yeh, you notice how fuel economy improves, and drops below 10L/100kms when u don't have air con and drive like a normal person...

weather was much hotter in syd a few weeks ago...so i had the a/c on alot of the time....

i also got booked about 2 weeks ago doing 91 in a 60 zone....fcuking undercover cops.... :o

so yeh, after that, i wasn't speeding much, didn't have the air con on alot of the time...and my fuel economy dropped to around 9.5L/100kms...

it's slowly rising for the last few days to 9.8L/100km because i haven't been driving it (catching the train)...so it's just a short 1km drive, and we all know how much petrol short drives uses..

also, i noticed that when we first start up our engines in the euro, our engines rev at around 1500rpm, and slowly drops to around 800....i'm guessing that's a normal feature yah? coz if it aint :eek:

i think thats normal when you first start up the engine as it has happened to many of the cars i have driven which dont just include hondas

was wondering does the fan in the euro affect fuel consumption?

i have been using it alot opposed to air con because it feels just as cold as the ac

a few friends and relatives have commented they like the fan as it feels as cold as ac!

zuiko
06-04-2006, 01:29 PM
LOL. When the Euro is set to fan ON - the aircon is actually working!

You have to press the AC button so that it displays AC OFF. Unless the display shows that the AC is OFF like this then it is actually working and you are using about 0.6 to 1L/100 km of fuel.

So its no surprise that it feels as cold. When you have the AC OFF - you'll see that the air is quite a bit warmer and more humid :)

14-15L/100km consumption, fuelling up 55L, but i also remain in high rev's here and then anticipating the opening for an overtake...

But like i say.. that's when i'm pretty aggressive.. otherwise.. it's around the 11L in city peak traffic.. heaps better on some smooth motorway runs,

Doing the motorway you can improve it heaps..

I just got back from a little Easter road trip. North Brisbane-Kingaroy-Hervey Bay-Gympie-North Brisbane. 753km travelled over two main legs with stop start driving in between (short trip cold starts included). When I filled up (just because fuel was cheap otherwise I would have kept going to see how far I could get out of the tank) I had only used 51.36 litres. That's 6.8ish l/100km. That includes the first 40km taking 90 minutes thanks to lovely Easter traffic, following caravans and boats up and down both Daguilar and Bunya ranges, the bumpy twisty sometimes one lane 150km stretch through Murgon from Kingaroy inland to Maryborough and air-con on 90% of the time. All I can say is this car is certainly a much different beast once the cat is warmed up! MY06 Euro Auto STD.

That's because those fuel economy numbers are tested while cruising on the highway and in the suburbs under as low a load as possible (very little acceleration). So the numbers you get are not representative with actual fuel consumption. Because of the torque convertor sacrificing revs for torque when driving under load in real life situations, the actual fuel consumption is much higher for autos than manuals.

hehe I managed to get 6.7L/km today driving in Oil-Crisis mode. On a full tank, it showed 740km->Refuel on the trip computer.

Basically I used 6th gear everywhere in 50km-90km zones (5th when going uphill), and only used 1st and/or 2nd gear to accelerate from lights.

Downhill start: 2nd->6th
Flat start: 1st->2nd->6th
Uphill start: 1st->2nd->5th

freakin sweet... :honda:

I wouldn't use 6th at 50kph even if it is flat. You are putting a huge stress load on the engine at those low revs. I don't use 6th unless it is 80kph+. On the Euro you will not hear the engine lug like many other cars (it will just accelerate slowly). Don't be deceived into thinking that this means the engine is not under stress.

Your manual says the suggested gear change speeds - don't go lower than those IMO.

It seems alright to me. I didnt accelerate in 6th at low speed, it was just coasting so its all good :thumbsup: Obvioulsy if I needed to accelerate or start hill climbing, I would bump it down in gear.

I mean I'm not going to do it all the time, I just wanted to see what the lowest possible consumption was. ;)

Just leave it in the normal gear - the Euro shuts off the injectors when you are not on the pedal anyway (so I am told - leading to that jerk some people dislike so much) - so whether you are in 6th or 4th it shouldn't make a difference.

Bit confused...

Does Coasting mean keeping the throttle steady to maintain the same speed? Or does coasting mean letting the car engine-brake with no throttle?

Yea I notice the jerk when I lift off the throttle (injectors cutting off), but keeping it steady seems normal, as does accelerating despite the slight delay.



So coasting at a steady speed does use fuel, otherwise the car would slow down if the fuel was cut off, therefore coasting in 6th uses less fuel than in 4th due to lower rpm.

I didn't know that it cuts off the fuel injectors, that's quite interesting. I think I might coast up to lights/stop signs more often. I always wondering what the "jerk" was. I feel like I've learnt something today.

Coasting usually means you are in neutral or the clutch is pressed. I wasn't meaning to refer to coasting - I was more trying to say that when you are off the throttle don't worry about whether you are in 6th or 4th. Sorry for the confusion - forget i said coasting - I will delete that word in that post.

And Billzor - it will definately help fuel consumption if you can roll to a stop as far away as possible without touching the pedal. The more you are off that accelerator the better - I think that goes without saying!

I see, thx for clearing that up.

Meh using 6th at 50/60km is too much hassle for what its worth anyway, i'd rather use 4th and pay an extra $2 at the pump... It was just a one-off thing I wanted to try.

Ahhhhh, yfin you have answered my long sort after Q, why the Euro has throttle lag. I got a whole lot of waffle from Honda who mumbled about digital equations converting to analogue with a triple bypass and a bowel replacement. So it is the lag from nil fuel to fuel flow, hmm, Honda should be able to resolve that. Thanks for that gem now do you know how to fix the problem? :)

I don't see it as "lag" - it is like a "bump" or "jerk" you can feel in power delivery (most noticeably when you are using cruise control up and down hills). It actually took me a long time to even notice this was happening it is so insignificant IMO. Play around with how you apply the throttle - sometimes if you are very gradual - ie tiny application and then gradual - there is no jerk at all. Give that a go.

Honda could change this but they aren't going to do it for your model or car alone - maybe future revisions of the vehicle might see changes. As the injectors shut off everytime you take your foot off the gas think of it as a good thing - saving you fuel.

By the way - I don't know what RPM the injectors cut off when rolling in gear. There might be some minimum RPM for it to happen? There also could be a minimum of time you need to be off the throttle - eg if you are on and off the throttle very quickly - there is no jerk aye? I noticed that. I think the ECU waits to see whether the car is definately going to be rolling in gear without throttle for a mininum set period before shutting off the injectors.

The slight lag when using cruise control doesn't bother me at all. Where I get annoyed is when I am in a parking mode and the car jerks hard when a slight amount of throttle is applied. I overcome this by coasting and feathering the clutch if necessary (which I hate to do). As I drove tourists around Europe I had to learn to drive smoothly that's why this throttle lag bugs me more than most. Maybe a tweak on the ECU might work. I don't think our local Honda dealer is up to it so are there any specialist between the Southern Highlands and Sydney or Canberra??

Possibly because there is fuel still in the injectors and fuel lines no where to go waiting to be burnt.


I thought the "throttle lag" ppl were talking about was the slight throttle responce lag when you push down on the accellerator due to the drive-by-wire system. confused again lol :p

Confused? yeah so am I. Are these two different problems or one manifesting in different ways?

I just did a drive from bris to syd then back again over last weekend, fuel economy was brilliant, infact there's probley enough juice to do the ~940k between Sydney and my house on the south side of Bris. Anyway, filled up after some bris city driving after returning, 925km on trip and put 60.51L of BP Ult back in the tank, which by my math is around 6.5L/100km.

Those figures look good but to keep to reality try doing a 4 fill up average driving normally, whatever normally is for you. Someone else said earlier not to tress the engine with too low revs. I seem to think that 2,000rpm is ok on a trailing throttle and 3,000 rpm at least if accelerating. These RPMs may need to be verified by those more enlightened (qualified) than me.

What do you mean by "shuts off the injectors"? Won't the engine stop if the petrol is stopped?

No, from what ive gathered, it shuts them off when the car is engine braking, but they turn back on at ~900rpm to keep idle speed and avoid stalling.
