260 GT

Sunoco 260 GT is a street-legal, oxygenated, unleaded gasoline designed for high performance street cars, muscle cars, classics, street rods, and the like.  With a 100 octane rating, Sunoco 260 GT will allow increased boost levels in supercharged or turbocharged applications compared to lower octane pump gas.

Sunoco 260 GT will not harm catalytic converters or oxygen sensors.  260 GT contains a comprehensive additive package for greater engine protection and reduced fuel system deposits.  It is compatible with two-stroke synthetic and mineral-based engine oils.  As with any gasoline, it should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of 260 GT is in excess of 1 year.

260 GT Plus

Sunoco 260 GT Plus is a high octane, highly oxygenated unleaded race fuel.  It is our highest octane unleaded race fuel which makes it a popular choice for racers looking for high octane in an unleaded product.

Because it contains more oxygen than is allowed in pump gas, it is for off-road and racing use only.  However, it will not harm oxygen sensors used in fuel injection systems.  Due to its high oxygen content, a richer air/fuel mixture is required to utilize the full potential of this fuel compared to a conventional non-oxygenated race fuel.

Sunoco 260 GT Plus contains additives to enhance shelf life and promote engine cleanliness.  As with any gasoline, it should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Properly stored, the shelf life of 260 GT Plus is in excess of 1 year.

Note:  exposure to sun light (ultraviolet light) can degrade the octane of this fuel and must be avoided.

260 GTX

Sunoco® 260 GTX™ is an unleaded racing fuel that contains no oxygenates and no metallic additives.  260 GTX is a good fuel for many applications that need more detonation protection than typical street gas provides, yet cannot use a leaded fuel.  It has been shown to produce repeatable power levels in small block V8 engines to 12:1 compression ratio, and will tolerate more compression in engines with smaller or more efficient combustion chambers.

260 GTX is not a street legal fuel and is for off-road use only.  However, it will not harm sensors such as oxygen
sensors used in fuel injection systems.  It is also an excellent choice where oxygenates such as alcohols and ethers are limited or banned by the engine manufacturer or sanctioning organization.

Sunoco 260 GTX contains additives to enhance shelf life and engine cleanliness.  However, as with any gasoline, it should be stored in opaque, tightly sealed containers where the temperature is stable.  Handled under such
conditions, the shelf life of 260 GTX is in excess of 2 years.

E85-R

Sunoco 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 68% to 79%
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 racers 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.

Green E15

Sunoco® Green E15™ is a highly oxygenated unleaded race fuel that contains 15 volume percent ethanol.  Because it contains more oxygen than most fuels, fuel system changes may be needed to extract peak 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.  It should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Properly stored, the shelf life of Sunoco Green E15 is in excess of 1 year.
