Don't waste your money you won't pick up anything, high octane fuel is for turbo, supercharged or nitrous powered cars. Also high compression set ups

You well be fine running 91-93 octane gas. Personally run 93

unless you have some one tune you for that level of octane you aren't going to be doing any more than you could do on 91-93... i'm not sure but i believe some race fuels contain lead and fuck up your o2 sensors and cat converters...
