Fuel Consumption Question

[Mark0]

i am getting about 80k's to half a tank atm

but i aint got my new ecu tuned yet...wil make a big diff

i would expect bout 300k's to a tank

[fatz]

yea i find with the gts its easy to keep boost at -300 but on the gtr one touch of the accelerator even if only a mm gets me to 0

rhino you must have a freek(what mods you got?)

Full exhaust with tuned length front pipes, and an ECU with the speed limited and I assume a few other things altered, and that is it power wise.

But your right one tap of the throttle and shes right on boost, I guess it's because I'm still in the early part of the ownership cycle where you notice every little thing about the way your car drives, what the gauges are doing and when etc.

At the moment I have done a mix of highway and stop start driving and I have done ~260K's on half a tank so thats about 12.5L/100K's with normal driving.

I find that not fanging it when cold does wonders for the fuel consumption. Generally I try to avoid giving it to the car when the oil temp gauge is below 70c, that way things are up to operating temp.

Hahhaha, I have two black marks about 2m long coming outta my "access road" at my place, to PROVE troy doesn't drive like Miss Daisy :D

You will get poor fuel ecconomy if you use 5th gear at speeds slower than 90km/h, I know some people who use it at 50/60kmh!

Not necessarily - I use 5th gear at 60km/h if I'm holding speed and/or the road is going downhill. The motor isn't labouring at all, in fact it cruises along quite nicely. It's actually pretty surprising how little throttle is needed to hold it at 60 in top gear, unless of course the road rises, in which case you use 4th (or 3rd if it's a hill rather than a rise). Personally, I've found as a general rule of thumb, if I can go another gear higher and not use any more throttle (or even less sometimes, as it doesn't need as many revs) then it'll use less fuel. You can sort of just tell when the engine is happy at a particular rev - do what the car feels like it likes. That's just the way I drive though, it won't work for everyone.

Mine gets given the herbs fairly regularly, and it's very unusual for it not to get at least 450-500km out of a tank, with the majority of that being ligth city driving (driving in the city but not much traffic). Most I've ever got from 65L is around 950km... all highway driving, and it was on the Xmas/NY holiday, on the way to the North Coast, up one of the most ridiculously over-policed highways in the state (Bruce H'way).

hehe that was me who used 5th at 50-60km/h. I stopped doin that now, but still didn't really improve economy. A new 02 sensor and i got about 30km more and still to do a new crank angle sensor. Currently gettin 330-350km from a tank with cat back, bov and filter.....stock boost.

I've been keeping a log recently and have got the following figures:

DATE | PRICE PER LITRE | NO. LITRES | TOTAL $ | DISTANCE | L/100km

22/10/02 | 96.7c/L | 26.75L | $25.87 | 218.3km | 12.254

26/10/02 | 97.7c/L | 47.41L | $46.32 | 384km | 12.346

29/10/02 | 93.7c/L | 47.29L | $44.31 | 395.0km | 11.972

All distances include heavy trafic, while the last entry included the cruise down the wollongong on the 27th.

What sort of figures are people getting with tuned Power FCs under similar conditions? I'm aiming at getting one in december after my final exam ever at uni (if I pass).

I have a air filter, exhaust, razo sticker, and standard boost.

Razo sticker, LOL. I find my SDU sticker hurts my economy so I'll be removing it soon.

Has anyone else noticed that the forum time is wrong?

[akeenan]

i dont know what everyone else is on man but i only get about 350km at the most out of a full tank before the light comes on

??? beats me

[Pva_Glue]

450 Km Full tank... with threshing and it's NA.

cheers

Check the time settings in your user control panel. It should be GMT +10 hours I think....

[XCUZME]

sir ricelot you forgot to tell everyone you get those economy figures on *REGULAR UNLEADED*

*gasp*

i got 400 easily per tank, sometimes 500..........even got 700 once and i drive like a frigging maniac, go the s15s (this is on 12psi too)

you perth boys must remember that city driving in perth (or canberra etc) is about the same as highway driving in sydney, the same level of traffic stop start etc.

there is no comparison for peak hour traffic in sydney, unless you're comparing speeds with the push bike weaving thru traffic, in which he eaaaaaaaaaaasily wins........damn onarun and his bike.

[Warpspeed]

Now there IS an interestin question.

How far can you get on a pushbike on a slab of beer ? If you fall off it does not count.

[fatz]

13l 100k's on the gtr this week working it

that is driving like a complete tosser

and the sab of beer about 5 k's laughing all the way fell of about five times although could have been more but cant remember

200Km for 30 Litres around town. Much better (260-80) if highway driving. Stock as a rock R32 GTR. Thats driving Camry style.

About 170-80 for 30 Litres if giving it a bit of a rev.

[franks]

can i just add here, yes after 3 months...a powerfc has made no difference to fuel efficiency, however, i do have 500nm of torque over the whole rev range!?

for the sake of the original question asked....reset your ecu, try and use the same petrol brand, bp ultimate or whatever and manage your right foot....

[ice180]

must be your driving frankie

[sven laptop]

Pardon my ignorance (I'm new & my Skyline is on the boat as I write), but what the feck is a Power FC or even an AFC for that matter?
