2024 Race Classes

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 these local stations only
