Sunoco EX02 is a highly oxygenated race fuel. EX02 is beneficial in crate engine, two-barrel engines, and racing classes with cylinder head limitations, as well as engines running at higher elevations. Due to its high oxygen content, Sunoco EX02 requires a 10 – 15% richer air/fuel mixture compared to most leaded race fuels.
Sunoco Standard is a 110 octane leaded race fuel that is commonly used in all forms of motorsports. It features a comprehensive additive package to enhance shelf life by improving stability and minimizing oxidation. Sunoco Standard is designed for compression ratios up to about 13:1 in conventional small block v8s, and combustion chambers. It is also a good choice for mild nitrous, turbocharged, or supercharged applications.
Sunoco Supreme is a 112 octane leaded race fuel designed for competition engines routinely operating over 7000 rpm. Supreme is blended to achieve a high motor octane number and fast burn speed to ensure engine protection lap after lap and pass after pass. Sunoco Supreme is designed for compression ratios up to about 15:1 in a small block V8s, and can tolerate higher compression ratios in smaller or more efficient combustion chambers. Supreme’s fast burn speed also makes it a popular choice for 2-stroke applications.
Sunoco M02X 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 %. M02X does not have to be drained from the fuel system after each use.
Sunoco HCR Plus is a high performance leaded racing fuel designed for racing engines with high compression ratios. It is particularly beneficial in sustained high speed/high load applications such as asphalt and dirt oval racing. HCR Plus is very resistant to vapor lock, ensuring consistent fuel metering from the green flag to the checkered flag.
Sunoco Maximal is a 116 octane, extreme performance leaded racing fuel designed for high-rpm racing engines with high compression ratios. Maximal’s fast burn rate makes in particularly beneficial in large-bore, large-displacement naturally-aspirated drag racing applications. it has also proven to be very popular in the highly-stressed naturally-aspirated big blocks used in truck pulling. Sunoco Maximal is very resistant to vapor lock, ensuring consistent fuel metering between passes.
Sunoco MaxNOS is the fuel of choice for extreme performance applications where “power adders” such as nitrous, superchargers, and turbochargers are utilized. Sunoco Race Fuels engineers added components to this fuel so it is better able to withstand ultra high pressure / high temperature combustion chamber conditions. MaxNOS was tested in the variety of drag racing applications ranging from mega-boost turbocharged small engines to multi-stage nitrous systems on mountain motors. It’s also a great fuel for supercharged pulling trucks.
Sunoco SR18 is our ultimate high octane, fast burning racing fuel. If you have a high compression, high RPM race engine, 118 octane Sunoco SR18 is your fuel of choice. SR18 is an excellent choice for drag racing and truck pulling, especially large displacement applications. For oval course and road racing applications, SR18 will tolerate the high cylinder pressures in racing classes where there are no compression ratio limitations. SR18 is the official spec fuel for NHRA Pro Stock class where consistency and power are crucial.
