MO2X

Sunoco 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.
