Standard Leaded

SDS

Sunoco® Standard™ is a 110 octane leaded race fuel that is used in many forms of motorsports. Sunoco Standard is designed for compression ratios up to about 13:1 in conventional V8 engines with iron cylinder heads. It can tolerate higher compression ratios in aluminum cylinder head applications or engines with smaller or more efficient combustion chambers. While most racers use Sunoco Standard in naturally aspirated applications, it is also a good choice for mild nitrous, turbocharged, and supercharged applications.

Sunoco Standard features a comprehensive additive package to enhance shelf life by improving stability and minimizing oxidation. It should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of Sunoco Standard is in excess of 2 years.

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

LEGAL:
For off-road and racing applications only. Not substantially similar to gasoline.

Supreme Leaded

SDS

Sunoco® Supreme™ is a 112 octane leaded race fuel designed for competition engines routinely operating over 7000 rpm. Supreme has a high motor octane number and a fast burn speed to ensure engine protection lap after lap and pass after pass. It is designed for compression ratios up to about 15:1 in small block V8 race engines and can withstand higher compression ratios in smaller or more efficient combustion chambers. Supreme’s fast burn speed also makes it a popular choice for 2-stroke race engines.

Sunoco Supreme features a comprehensive additive package to enhance shelf life by improving storage stability and minimizing oxidation. It should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of Supreme is in excess of 2 years.

E85-R Unleaded

SDS

unoco E85-R is an unleaded racing fuel containing 85 volume % ethanol. It can only be used in fuel systems designed specifically for E85 blends. 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. Conventional E85 can vary from about 51% to 83% ethanol or so but rarely contains 85% ethanol. Conventional E85 can also vary seasonally; the composition of Sunoco E85-R race fuel does not change. The non-ethanol portion of Sunoco E85-R is comprised of highly-refined race fuel hydrocarbons for stability and consistency. Sunoco E85-R is the racer’s fuel of choice where E85 fuels are allowed.

Sunoco E85-R does not contain metallic additives and will not harm oxygen sensors. It should be stored in dark, tightly sealed containers where the temperature is stable. Handled under such conditions, shelf life is in excess of 1 year. Check with your fuel system and fuel container manufacturers for compatibility with ethanol and E85 blends. Please note that due to the high oxygenation of E85-R, the octane values are estimated.
Note: the octane ratings for E85-R are estimates. The conventional ASTM laboratory octane tests cannot accommodate the high oxygen content of fuels like E85-R.

DISCLAIMER:
Legal in California only for racing vehicles in sanctioned racing events. Octane is estimated.

LEGAL:
For off-road and racing applications only.
