2024 Race classes
Spec Fuel: VP MS98L or 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:
