leaded fuels will coat your O2 sensors and make them go bad quickly. There is no reason to run race gas. The only reason I ran some race gas in my car when I went to the track was because I was spraying 125 shot of nitrous on 15° timing and i didnt want any detonation..... I was running 110

Higher octan doesn't nessesarily mean more power, the higher octane just means it takes higher temperatures to burn. It will help eliminate spark knock under most applications. On a stock or lightlty modified car, using race fuel would be a waste and would mostlikely lose power from it. Optimal ocatan would be under 100 for stock. But we have all tried race fuel....just don't do 100%, maybe 25% race and 75% 93 to give you a boost, but you will see it won't really help..smells good though.
