i know we are supposed to run 93 octaine in our cars, but where i live supreme is only 91. i really dont believe in octaine booster, so i've been using the only thing available to me.
i went to the local 76 today and what did i see? RACING FUEL!!! 100 oct. what i want to know is, how much is too much? what if i fill up with it? what do you think would be the ideal mix?

 

100 is not too much... it's a waste of money if you're gonna fuel up your car w/ it all the time though. my suggestion... run 91 regularly and put in 100 octane about once every month or two... just my .o2

 

Correct me if I am wrong, but I believe the owners manual says 91 octane is recommended. 100 is just a waste for everyday driving.

 

Manual reccomends 91 minimum. Only way 100 will help you is if your computer is programmed for it...
