We recommend VP NO2 race fuel for fogger or three-stage nitrous oxide applications with CRs up to 18:1. It bridges the gap between VP’s C16 and C23. VP NO2 has both higher octane and lower specific gravity than most nitrous fuels. As a result, it may require enriching the fuel mixture more than would be required for C16.
