crfsonly wrote:on the race fuel they are correct. unless it is oxygenated race fuel just having a higher octane won't increase performance. now if you have a high compression piston than higher octane will help prevent early detonation which is essential for not imploding your motor. if it's a stock motor premium pump gas works just fine.
