Re: race gas
Sure you can. However, do you have a custum tune setup for race gas or a high boost/nitrous setup requiring the extra octane? If the answer to all of those is no, then race gas is useless for you. In fact, if you have just a stock tune in your car, then anything over 87 octane is just a waste of money.
Race gas won't make you go faster without your car being tuned to take advantage of it.
