how do u guys know about ur fuel consumption?
Either way, 500-550km is shit. Even if i drive spirited, ill get atleast 700km. I drive to and from work everyday in peak hour traffic and get 800km, and last weekend heading down to the snow fields from sydney i got 1000km
Some pretty good mileage from you guys. And here I was beginning to worry about the petrol price!
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!)Quote:

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.Quote:

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.

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).Quote:

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:Quote:

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.
I can't stay below 4K rpm :D That's why my fuel consumption is like 14L/100km or so, haha! I had 3/4 tank initially, and how a little under 1/4 of a tank, and I've done around 270km or so. Not to mention each of my trip is less than 20 mins of driving.
excellent tips aaronng, learnt a few new things :)
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.
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.
iumm just ignore what i just said, i understand what your saying now about momentum of car.
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.
I think from now on ill only use Vortex98..i usually do but the petrol station near by doesnt have it everyday...so i miss out alot.
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...
lol, thanks for the driving lessons :D
i filled up yesterday on ultimate.....the pump said i filled up 48.88L....which mustve meant i had 17L left to go until i was completely empty
i filled up after travelling 517kms.....with 17L left in the tank .....is that good for city driving?
btw, how do u guys measure how much petrol u use by doin that 9L/100km thing? how do u measure ?
I think my post at the bottom of page 7 of this thread covers what you are asking.Quote:

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.
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.
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.
More fuel = more weight ;)
Man isn't petrol expensive these days! it costed me $70 to fill her up!! gotta watch out the heavy leaded foot!
$70? :eek:
My civic usually cost half that!
Ha! try Optimax at $1.34 a litre!!
54 litre = $70 something!
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.
Model 05 Luxury
no mods
kms 6,000
Driving conditions: Country sealed roads 20%, 5% city off peak, 75% Expressway and fast B roads. It gets Vtec'd 4 times a week average. Mostly sitting on and indicated 120kmh in 6th.
Average consumption : 7.8 L/100kms.
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).
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!
What car does your friend drive? An Euro as well?
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.
Yes, my friend drives Euro as well, not one, but plenty of them!!. In melbourne, I see as many Euros as Commodores :(
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.Quote:

Are you using 98 ron? When was the last time your air filter was replaced or at least junk removed?
I'm using BP Ultimate, which is 98 octane. I haven't done my 5k service yet. so I dont know what kind of junks are there in my air filter or change the air filter.Quote:

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 =(Quote:

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)Quote:

I guess by turning off A/C 80% of the time in winter months helps with fuel consumption figures.
I keep my air con/climate control off as much as I can.
damn...thats impressive...Quote:

No idea how I got much better fuel consumption than all of you.
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.
wat ron is Vortex? 95
they are putting 10c surcharge on top, just rediculus
how is this calculated accurately?

Dont accord euro's have one of the most amazing feul efficieny ratings for a 2.4 litre car? Somewhere around 7L/100KM average if i remember correctly... how come most guys are getting 9-10 and even more L per 100KM:confused:
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).Quote:

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 consumptionQuote:

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.
So very true only if the car was in true perfect conditons every day 365 days a year would you get the quoted fuel consump& I doubt that would ever happen to any of us!Quote:

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)
For the first 3 years and given the fact that we follow the service schedule, our engines should be in pretty good condition that we won't have abnormally high fuel consumption. :)Quote:

I manage to get 312km and its not even 1/2 tank yet (still got alot to go!), while I drive in non busy streets normally (Canberra 'traffic') i only get 290 for 1/2 a tank... bare in mind, canberra 'traffic' i mean i only stop at 1 traffic light and its all roundabouts the whole way...

Try revving it high on non highway driving... :)

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.Quote:

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.
I think you should get off the crack, not anyone else here.Quote:

Liberty 2.5i using platinum plugs, 98 RON fuel and 5W-30 engine oil - trip computer sitting around 8.2 to 8.4L/100km.
For fun I reset the computer this morning and drove down the SE freeway in Adelaide and then out to norther suburbs at 8AM. Took 45mins. Obtained 7.2L/100km. Would have been 7.0 if I hadn't switched taken off from the lights like I did a few times.
The Euro is relatively thirstier than the Liberty from what I have read. It's a real hard struggle to get the Lib into the high 9's let alone above 10!
On the freeway, I get 7.0L/100km as well. But for all city driving, it's still 9.5L/100km. Maybe if I have a mix of freeway and city, it should be about 8.xL/100km.
BTW, it's shitty that the Euro doesn't have a trip computer to calculate fuel consumption!
The trip I described only had about 15mins max of highway driving (half downhill too though)
Just took my first reading...9.3L/100km of which 98% was city driving and 2% was highway. AT Euro so I'm quite happy. :)
If that was 2/3s city driving, then yeah, the Liberty seems to be pipping the Euro on fuel economy! Oh, and if you have tips on decreasing your fuel consumption, please feel free to share it with us. So far, manual Euros have been getting about 9-10L/100km city, while the poor autos get 10-12L/100km (did I get those numbers right?).Quote:

Certainly not what I heard from other Subaru owners.Quote:

Whoops, missed your post. Yup, you have lower fuel consumption.Quote:

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.. :(
interesting. always thought BP ultimate, was, well, the ultimate :D
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:

Is this only applicable to Automatic?
If so - I am guilty.. :(
Too much grand prix starts chasing magnas and mazda6 these days !
