Whats the highest octane unleaded race fuel avaliable and what is the name of it? I talked to the guy that sells the fuel at my track and he said that the highest unleaded race fuel was 104 octane and that c16 (116 octane)fuel was leaded.

correct me if im wrong, but i think after 108 the gas is leaded. lead gas is bad to run in your car, it will ruin your 02 sensor and give you poor performance.
