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

wont do anything but drain your wallet faster.
hell most gsrs run fine on midgrade

wouldnt that just make your engine run hotter, maybe a little bit faster, not worth the money i would say

I didn't think it'd do much, but i figured i'd ask

All higher octane gas does is resist preignition (also kows as detonation or knock). If your car is not detonating at your current octane, why change to something you don't need?

so you can advance timing more.

Higher octane actually burns colder.

Higher octane actually burns colder.


WHAT?!?!?! that makes no sense. Well i feel dumb.

I don't know about colder, but it does burn slower and resists burning more than conventional gasoline

Yeah, it actually does. Learned it while attending NTI. ITs funny all these people putting in high octane gas in a car that calls for lower octane. Since higher octane gas actually burns colder, it is actully increasing carbon buildup in a lower compression engine. The lower compression engine needs the extra heat from the lower octane gas to burn off the carbon. Yeeh, higher octane fuel burns cleaner, but in the long haul will led to more carbon in a low compression engine. If you think about it, a car with high compression is going to create a lot of heat. It is going to need something to cool the cylinder down to a reasonable temperature. The higher octane fuel takes a lot more heat to self combust than a lower octane fuel. So it reduces preignition.

hummm, i guess that makes sense. thanks for the explination
