Power your engine with Sunoco unleaded fuels

Sunoco GP2R is an unleaded racing fuel blended specifically for 2-stroke racing motorcycles. GP2R meets the stringent requirements of the FIM (Federation Internationale de Motocyclisme). Sunoco GP2R has an (R+M)/2 octane rating of 94 and contains 2.7 weight % oxygen (maximum). Sunoco engineers designed GP2R to provide crisp throttle response while maintaining the excellent fuel stability characteristics racers and racing organization expect of Sunoco.
Sunoco GP4R is an unleaded racing fuel blended specifically for 4-stroke racing motorcycles. GP4R meets the stringent requirements of the FIM (Federation Internationale de Motocyclisme). Sunoco GP4R has an (R+M)/2 octane rating of 94 and contains 2.7 weight % oxygen (maximum). Engineers at Sunoco Race Fuels designed GP4R to provide increased energy content while maintaining the excellent fuel stability characteristics racers and racing organizations expect of Sunoco.
Sunoco FR is formulated to meet FIA and FIM race fuel specifications. Sunoco FR is an unleaded oxygenated race fuel that performs well in turbocharged engines rewuiring a 96 octane fuel as well as in air-restricted naturally aspirated engines that can benefit from a fuel containing additional oxygen.
Sunoco CF is a 96 octane unleaded racing fuel that complies with fuel regulations limiting oxygen content to 2.7 weight %. Although CF is not a street-legal fuel and is for off-road and racing use only, it will not harm oxygen sensors and catalytic converters and works fine in computer-controlled race engines.
Sunoco M02X Unleaded is a fast burning oxygenated racing fuel designed for excellent throttle response. It is particularly beneficial in high compression, high rpm 2- and 4- stroke applications such as motorcycles, all-terrain vehicles, and other small engine applications. It complies with fuel rules limiting oxygen content up to 2.8 weight %. M02X Unleaded does not have to be drained from the fuel system after each use.
Sunoco 260 GTX is an unleaded racing fuel that contains no oxygenates and no metallic additives. It has been shown to produce repeatable power levels in small block V8 engines with compression ratios up to 12:1, and will tolerate more compression in engines with smaller or more efficient combustion chambers. 260 GTX is also an excellent choice where oxygenates such as alcohols and ethers are limited or banned by the engine manufacturer or sanctioning organization.
Sunoco Green E15 is a highly oxygenated unleaded race fuel that contains 15 volume % ethanol. Because it contains more oxygen than most fuels, fuel system changes may be needed to extract optimal performance from Green E15. Sunoco Green E15 contains a comprehensive additive package that helps keep fuel systems clean, enhances shelf life and reduces fuel system deposits. Check with your fuel system and fuel container manufacturers for compatibility with ethanol blends.
Sunoco E85-R is an unleaded racing fuel containing 85 volume % ethanol. Because it is highly oxygenated and requires increased fuel flow compared to conventional non-oxygenated fuels, consult with your fuel injection system or carburetor supplier for correct air/fuel ratio calibrations. Sunoco E85-R is blended to consistently contain 85% ethanol. The non-ethanol portion of Sunoco E85-R is compressed of highly-refined race fuel hydrocarbons for superior stability and consistency. Check with your fuel system and fuel container manufacturers for compatibility with ethanol blends.
Sunoco 260 GT is an oxygenated, unleaded gasoline designed for high performance street cars, muscle cars, classics, street rods, and the like. It is street-legal in most states except California. With a 100 octane rating, Sunoco 260 GT will allow increased boost lives in supercharged or turbocharged applications compared to typical premium pump gas.
Sunoco SS 100 is an unleaded high octane gasoline that is street-legal in California. Its 100 octane rating will allow increase boost levels in supercharged or turbocharged applications compared to premium pump gas. Sunoco SS 100 can be used in high performance vehicles both old and new. It can also be used in applications such as motorcycles, ATVs, go-karts, and other smaller engine vehicles.
Sunoco 260 GT Plus is a highly oxygenated unleaded racing fuel. 260 GT Plus is not street-legal and is for off-road and racing use only. However, it will not harm sensors such as oxygen sensors used in fuel injections systems. Due to its high oxygen content, a richer mixture is required to utilize the full potential of this fuel compared to a non-oxygenated racing fuel. Exposure to light can degrade the octane of this fuel and should be avoided.
Sunoco Optima is a non ethanol gasoline specifically enhanced with stabilizers that keep Optima fresh for up to 4 years with properly sealed containers. Optima is perfect for small engines that are infrequently used to keep carburetors clean during downtime. Optima will not precipitate waxes as seen with normal pump gas fuels that clog up fuel systems and parts. Optima is your choice for first pull dependability of your small engines.
