CARB: The California Reformulated Gasoline Regulations (RFG) found in Title 13 of the California Code of Regulations (CCR), Sections 2250-2273.5 require California gasoline sold, offered for sale, supplied or offered for supply as a motor vehicle fuel to meet certain and specific chemical content and physical property specifications, including, essentially, a zero lead (Pb) content requirement. Leaded and unleaded racing fuel that does not meet the California RFG specifications (non-complying racing gasoline) can only be sold, offered for sale, offered for supply, or supplied for use in true, competition racing vehicles. The retailer, i.e. service station, speed shop, auto parts store, fuel distributor, and race track fuel dispensing facility, etc., who is selling or supplying this non-complying gasoline must “take reasonable prudent precautions to assure that the gasoline will be used only in racing vehicles.” If the vehicle this fuel is to be used in is registered or licensed for on-road or off-road use, this usually indicates that non-complying racing fuel cannot be used in it and the sale or supply of the fuel should not take place. CARB will consider this and all other relevant circumstances to determine if “reasonable prudent precautions” were followed in any particular case. In evaluating whether “reasonable and prudent precautions” were followed, CARB will consider whether the retailer kept a record of each sale of non-complying racing gasoline and whether each sales record contains the above information.
