Best Answer

This depends on the engine. If you are running a stock engine with stock compression, you should be fine on regular 87 octane pump gas. The higher the compression ration, the greater the need for higher octane fuel. 8.0 to 1 should run at least mid grade; 8.5 to 1 and higher should use 92 and higher. Anything loopy like 10 to 1 should run race gas. Any solution with a turbo should run premium fuel.
