Race gas on stock GSR???

All of a sudden, there is a gas station right in the heart of the city that decided to sell Mach 100 premium race gas. IDK why, but anyway....


What would happen if i ran my stock GSR w/ basic upgrades I&H on 100 premium race gas?? Would there be a difference?? If so would it be noticeable??

If anyone has tried this let me know....also what is a good price per gallon for 100+ Premium gas?? Here it is $3.95 per gallon!!

Thanks

You certainly wont gain any hp, unless detonation is present. I would suspect you to notice no difference, to possibly even a small loss in hp. Theres no point in running 100 octane when the pcm is tuned for 87. $3.95 seems high to me. 108 here locally is $3.49.

I'm curious....no pumps around my town have race gas but there is a race track nearby. Would I be able to just go there and obtain something at least 100?

I have no need for it now but I may in the very near future.

yeah, you can pretty much guarantee if there is a drag strip, theres going to be race fuel at the nearby gas station. I think the gas station near my local drag strip carries 109.
