[Euro] Fuel Consumption

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

Model: Euro 6Spd Manual
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

I know this is a bit sad, but i have all my fuel consumption info in a spread sheet. Including by fuel type.

Coool! I use a spreadsheet too, but I didn't do the graphs. I might give that a go.

I must say it is SAD, but for some reason i like it......

Model: 03 Euro Manual Lux
Mod: front lip and rear boot spoiler (increase coefficient of drag)
Odometer: 31527km
Highway:60%; suburban road: 35%; Peak hour traffic:5%
Driving style: 90% change gear below 3500rpm.
Number of people on board: 80% driver only; 15% 2 people; 5% 3people or more
Fuel: Shell optimax 90% of times ; BP Ultimate 10%
Average: 8.6L/100km... very steady throughout.

Model: Euro Luxury 6Spd
Mods that could impact consumption: 110kg load :wave:
Kms: 20,000kms
Driving conditions: 100% city and suburbs
Average Consumption: 11lt/100

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.

must have dropped a 6ltr v12 in their test car

6ltr V12 like a Maserati gets about 1.8Km/L

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)

No matter how hard I drive, I haven't seen my fuel consumption go over 11L/100km yet.

maybe their test car is running rich like mine.

Simply an amazing post. I personally wouldn't make a habbit of running the fuel tank dry but thumbs up to this guy. :thumbsup:

yeah i gone 102kms with fuel light on..honda i think fixed this in the CRV ( about same distance with light on for 02 model) now it goes less. but yeah...top write up..

Gee the consumption levels aren't too bad for the new Accords, I thought it would of been abit higher.

Ive only had 2 tanks so far. Im getting 9.5l during run in (first 1000km) which is almost exactly 50% city 50% highway. Id expect to be getting 9 or less after another 5000-10000kms. I drive fairly enthusiastically!

u guys have got it so good. ive just used half a tank and travelled 150km. on the freeway to sydney i can use the same amount of fuel and travel 400km.

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.

Model: 6mt
Mods that could impact consumption: comptech icebox
Kms: 15,000kms
Highway kms (steady 90kph+)-estimate %: 5-10%
Average Consumption over life of car: 10L/100km

Peak hour driving in morning and arvo/night through Sydney City itself.
Occasional (1st gear) red line off the lights when necessary or upto about 4-5Krpm shift. Then 2-3k shift other gears.

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.

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.

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.

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

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..

Yes.. i've heard that Optimax leaves a lot of crap which can cause issues...

so optimax is no good? I was gonna use Shell.....

Anyway, picking up my car in 2 hrs 15mins!! YEAH!

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?

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.

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.

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.

aaronng: thank you for the info

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.

just did my first tank of fuel, till the light came on

estimated about 13L/100km very light footed, mostly highway too...

im hoping this will go down to closer to 10L/100km but we will see how we go over the next couple of months.

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.

Cool, thanks for clarifying that! Your economy sounds great.

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.

Auto vs Coladuna's manual will make a difference too.

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 drive auto.
450 to the light

When i drive HARD the car just chews fuel. Can use an eigth of a tank in half an hour.

Any numbers for highway travel? Anyone done a full tank from EG Syd to QLD?

Just picked up my car, no idea what fuel the dealer put in... but so far manage 170km with more then 3/4 tank left...

I LOVE MY NEW CAR :D

I've done a sydney-canberra-sydney on 1 tank before. Calculated and I got 7.2L/100km

Sounds good, grats on the purchase! Time to update your profile and upload some pics? :) I just added an interior pic to my own collection..

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).

My 1st full tank (top up from factory's 1/4 tank of whatever's in there with optimax). Got 490km out of 58L.

Still breaking in the engine with varying throttle accelerations to varying RPM's and engine braking....

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....

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.

Thanx Aratahu! Profile updated with pics ;P just a shot with my camera phone and paintbrush touchups... don't have anything else to use at work! Will fix it up when I have the chance!

Model: 2004 Euro 6sp
Mods that could impact consumption: Keep tires pumped up; I used 37PSI Front and 35 PSI Rear
Kms: 23K
Predominantly city driving with good dose of freeway
Average Consumption over life of car: 9.31L/100Km; Best 7.43L/100Km; Worst 11.46L/100Kms
No noticeable difference with seasons (even with lots of air con in summer) .
Fuel economy extremely consistent

Is this what it should be?

Didn't realise that there would still be around 10L left after the fuel light come on...

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.

:confused:

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.
