Fuel Economy Question

[Tebie]

gday

i just want to find out how many k's people are getting with a full tank of regular or premium unleaded out of their R32 GTS4 or GTS-T? i usually get around 300k's and thats mainly city driving... my car is basically stock

[mad082]

sounds about right to me. i got a 33 gts-t, with optional lead foot, 14psi, fmic exhaust and i get about 250-300kms of spirited driving.

[Tebie]

really?

when i first bought the car i thought i should easily get 400 k's out of a full tank

the guy i bought the car off said it was running rich so i thought it definatley should be able to get more k's

but since i had the fuel pressure adjusted to what it should be their hasnt been much of a change and i thought something may have been wrong...

hi there mine gets 350 around town boosting it heaps, freeway ,or highway up here i easily get 550 out of a tank ,keep in mind that its only an auto if it were manual i reckon it'd be even better

In my 32 gtst i'm getting about 320-380km out of a tank with mixed city/hwy driving...if its freeway cruising...i'll get upwards of 450kms to a tank if i run it dry...

[mad082]

how much of a change in fuel pressure was made? and was it up or down. if the pressure was raised then economy would get worse. i get about 350-400k's to about 45L (about 12L/100k's) out of my missus SSS pulsar (natro sr20), and turbo cars chew much more fuel.

also they run pretty rich from the factory. just get a remap or a safc2.

[Tebie]

i dont know what the fuel pressure is set at now but i know greg from autosport lowered by 20psi i think...

ever since then i do get more k's because i used to struggle to get 250 k's but now it varies around 300 to 350k's depending on if i use premium or regular fuel...

currently my car has done just over 250k's with using half a tank of petrol and all that is highway driving

you run your car on regular? seriously not a good idea. not a good idea at all.

[Tebie]

i used to....

i was told to use premium from now on

[barnoon]

I get on average about 300ks to a full tank but im a lead foot and thats city driving, If I drove nice and sedately I could probaly manage 400ks but wheres the fun in that

Used to get 300km before major service + ecu reset.

At the moment sitting on half tank indicator with 200km clocked up

You cant use any old premium either, you have to use a 98 octane premium fuel.

I get about 450km to a tank. Have you increased the boost on your car?

[mad082]

you don't have to use 98ron fuel, but it helps. if the car is basically stock you should get away with it, but i'd use 98ron just to be on the safe side.

I have a 32 GT-R, but i'll throw in a post anyway- on my last tank of fuel (1/2 Ultimate, 1/2 Optimax Extreme) i got 500km out of it, and just under half of that was cold start/city driving

gotta be happy with that from a GT-R

my friends Stag won't get better than around 300km to a tank no matter what

[mad082]

on the highway i get pretty good economy. i did a trip to brissy and back (about 380k's, with a little bit of WOT with 3 other people in the car (not high speed, just full noise up to the speed limit), and another 30km's of city driving, so 410km all up) and used 45L of fuel = just under 11L/100k's.

[Tebie]

no i havent increased the boost

and it is basically stock....

this tank of fuel i got now, 1/2 was highway driving and the rest cold start city driving and i am just about to crack 360k's and i am basically out of fuel...

i usually seem to get less k's on a tank of 98 octane then 95....

[mad082]

what you also have to take into account is that you have a gts 4, which is heavier than a gts-t, and you are running your power through a 4wd system. this takes more power to turn than a 2wd system, so you would have to use slightly higher amounts of throttle to do the same speed as a 2wd.

ditto with every one else, even though mine is modded. If i take it up to the black spur and drive it around pretty hard i get about 320 bare min per tank, if i nurse it i can get 420, get about 380-400 in the city, which is sort of all-around driving

[Mr GTS4]

i get about 350 odd per tank of premium.. not great but i got highflowed turbo with 15psi, 550hp fuel pump and the rest so yeah.

[eMsta]

my r33 has gets around 350 (out of 50 ltrs) on average - thats driving like a grandpa, normal and spirited

best i have gotten was 420 (out of 50 ltrs)
