G'day All.
I wonder if Shell have changed anything in there fuel the last two tanks of fuel I have had over 500kms normally I get between 425 - 450kms I haven't changed the way I drive.

STI injectors
STI top mount

I've been using Shell only for about 3 months straight now, with just over a full tank per week.Can't say I've noticed any difference in my mileage recently, although I have noticed some pretty impressive economy numbers in this time. I will make a mental note to check the exact figures this week and let you know

Quick update; I got 520km from the last tank before the petrol light came on (~8.8L/100km). I wouldn't say it was any different to usual, was pretty much 50/50 freeway/city driving. The car does seem to drive well on the VPower though

I get around 450-500 each tank have got over 500 a few times and that's with a pretty heavy foot.

That's a tuned 05 sti, TBE, Walbro.

Well it would be pretty normal then - 2.0L vs 2.5L on city driving

Yeah its crazy I know...I need to clock it one more time to see but I was shocked too.
90%of the time I always wait for my car to warm up before driving, not sure if that has anything to do with the low kms....Im a bit heavy foot like grapejuice also.
Next fill I'll clock again to be sure

Edit: I've only ever clocked the fuel once(2weeks ago) and can't remember if there were any events that week... def need to clock again to be sure

I would most likely say that you forgot to carry the one somewhere in your calculation RJ. Like Ross, cammed, stroked, punished, and still get over 400, sometimes close to 500 per tank.

Have to agree, if you clock it and you get anything close to 300km a tank. You've got issues.

I don't think I've ever even been close to using less than 400km's.

And the amount of fuel you would use letting your car warm up at idle would be fuck all.

If I was getting 300km's to a tank that would be costing me almost 30 bucks extra a week.

30x52 = $1560.

Re-tune. Worth it.
