Moto RP6

Sunoco Moto RP6 is a highly oxygenated unleaded race fuel that excels in high RPM powersports applications including motorcycles, ATVs, and UTVs.  When Moto RP6 evaporates, it absorbs more heat than typical fuels and can help engines run cooler in both 2-stroke and 4-stroke applications.  It is thermally stable compared to competing fuels and can be relied on lap after lap, event after event.  There is no need to refrigerate Moto RP6, and no need to drain and flush the fuel system.  With Sunoco Moto RP6 in the tank, you and your team can focus on winning!

Sunoco Moto RP6 is not premixed with 2-stroke oil so you can add your preferred oil if you’re running a 2-stroke engine.  Moto RP6 contains a comprehensive additive package that helps keep fuel systems clean, enhances shelf life, and reduces fuel system deposits.  It should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Properly stored, the shelf life of Sunoco Moto RP6 exceeds 1 year.  Because it contains more oxygen than most fuels, tuning adjustments may be needed to extract optimal performance.


Legal in California only for racing vehicles in sanctioned racing events.


For off-road and racing applications only.
