    Event requirements

    Race Officials follow the 2024 WKA Technical Rule book except where noted. Arco 87 pump gas. See individual class listings for specified fuel. Mixing of fuel brands or types is ILLEGAL and will result in a DQ. Any additives, whether they are performance enhancing or not, are ILLEGAL and will result in a DQ (with the exception of manufacturer additives present in pump gas from the pump). It is advised to purchase pump fuel the day of the race. A test sample of both fuels will be taken that day and used by Post Tech for comparison. Legal 87 octane pump gas can be purchased at this local station only: Arco (AM/PM Market) 2985 Rubidoux Blvd. Riverside, CA 92509
