Race Gas

Unless you are running a higher compression pistion or have a shaved head, or hell even a tune requiring race gas, you are LOSING horsepower by running it, lower octane

Unless you are running a higher compression pistion or have a shaved head, or hell even a tune requiring race gas, you are LOSING horsepower by running it, lower octane fuels burn hotter and burn faster creating more horsepower. Not only are you losing horsepower but since the fuel isn't burning as thoroughly you are leaving bigger carbon deposits that will eventually gum up your valves and leave wealths of carbon on your piston creating poor engine performance.

The only race fuel that may even be worth trying in a non modded Z would be Oxygenated race gas, but even then its only good for a couple horsepower and its 9-11 bucks a gallon.
