260 GT PLUS
Sunoco 260 GT Plus is a high octane, highly oxygenated unleaded race fuel.
Because 260 GT Plus 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. Due to its high oxygen content, an increase in fuel flow is required to utilize the full potential of 260 GT Plus compared to conventional non-oxygenated fuels.
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.
Note: exposure to sun light (ultraviolet light) can degrade the octane of this fuel and must be avoided. Contains octane boosting additive, MMT.
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 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. 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.
