vetwhat said:what kind of gas mileage can a ls2 gto get with a light foot city/hwy and what grade of fuel will the ls2 run ok with?
also can the "skip shift" be overridden?
It is taking a risk on the engine is the main reason we are so adament about it. Yes the system can compensate for it. But it is still a HUGE risk for the THIRTY FIVE THOUSAND DOLLAR CAR!!!!noz34me said:Since I haven't taken delivery of my GTO, I can't comment how the mileage would increase or suffer with lower octane.
Joined a CrossFire forum when I thought I was getting one of those. Some of those folks actually saw mileage increase with lower octane gas.
No question you won't be pumping out the same amount of horses with lower octane, but you're starting with 400 here, right?
One thing I've found on both forums is that this is a subject that many people are very passionate about (pro premium vs. it doesn't matter).

With my '04 I never even saw 24 MPG, best on a long trip was 23 and change.rrathea said:I run premium only (93 octane) in my 06. On a recent trip from Tampa to Orlando running 70mph I got 25.5!! Was running cruise and no AC (it finally cooled off down here). I only average 14 - 15 in the city.
