Fuel Consumption ???

[dantmcc]

G'Day everyone,

I recently bought a 1995 R33 Turbo Skyline and got a bit of a surprise at how thirsty it is (compared to my Toyota Corolla I traded it for!).

Without driving too aggressively, I only manage to get 290 km from 50 litres of premium unleaded petrol - does this seem about right for my car, or do I need a tune up?

Thanks for the advice ...

look at replacing the O2 sensor, there's quite a few threads on this here, just do a search.

some people get guzzlers some don't.

For the majority of driving time I'm sitting on or below 3000rpm and always change at 3000 rpm. Doesn't help my consumption though. I get about 330-350 to a tank.

I've tuned, replaced o2 sensor but nothing has helped.

Just gotta accept that for some reason, some people get good consumption and others don't.

don't accept it, i get about 400km to the tank with an untuned PFC and an idle thats fu(t and runs at 1500rpm, also runs really rich cause the the lack of tune, so yeah something wrong, hoping to scrape closer to the magical 500km per tank with a tune, i'll let ya's know

Try running a 98octane fuel. See if that helps. But my rb20 in my 1450kg car gets 9.9l per 100kms. Id be worried and start looking for the problem.

your running very very rich to only get 290km on 50 litres. Im running rich and get 400km on a full tank.

Is this city driving only or mixed? Also remember boost comes on fairly early (approx 2300ish rpms on std turbo) so perhaps driving normal for you may mean changing gears at 3500rpms when the turbo is really on boost which equals more fuel consumption. But thats only a possibility i threw up in the air...

I used to get 450km to a tank in my gts-t, and i used to get approx 400-450 km to a tank (same size) in my gtr

So if you're getting 290km, theres something wrong. O2 sensor would be the first thing to check

thanks for the tips everyone, i'll look into the problem further, starting with the 02 sensor. 400km per tank compared to 290km will save me a lot of dough!
