Race Gas



if its leaded it will destroy/harm the stock 02 sensor. Your not going to take full advantage of the race fuel without a tune anyway either.
 
Unless you have a bunch of KR to get rid of race fuel is pointless...and like was said can only taken true advantages of with a tune...93/94 is the most I'd run in a GTP on the street IMO...that's enough octane...plus race gas would only hurt you.
 
There is no reason to. I run 91 and not only being cheaper than race gas.... It makes more sense.
 
it will help clear up some knock, if you have it. nothing wrong with higher octane. i would throw a splash in there if you were going to race. to much leaded fuel will burn up the 02's

but it wont benifit you that much to fill a take up with it, just a little bit to raise octane a little.
