Race cars on track

MO2X® is an oxygenated racing fuel designed for excellent throttle response in high compression, high rpm 2- and 4-stroke applications such as motorcycles, all-terrain vehicles, snowmobiles, and karts. It complies with sanctioning body fuel rules limiting oxygen content to 2.8 weight %. MO2X does not have to be drained from the fuel system after each use.

Sunoco MO2X contains additives to enhance storage life. It is not a street legal fuel and is for off-road and racing use only. As with any gasoline, it should be stored in opaque sealed containers where temperatures are stable.


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


For off-road and racing applications only.
