Sunoco EPX E85 Race Fuel

Sunoco EPX Extreme Highly Oxygenated Unleaded Racing Fuel contains 85% Ethanol and Methanol. 

Sunoco EPX is an extremely highly oxygenated unleaded racing fuel. At 34% oxygen, EPX
contains more oxygen then E85-R. Of course, you will need to make sure the fuel system can
meet the increased fuel flow demands to take full advantage of this exciting new fuel.

Drag racers using highly boosted “import” motors like Honda’s K-Series and Toyota’s revered
2JZ variants, drag racers running big turbos and blowers on domestic motors including Ford’s
Coyote and Modular motors, GM’s LS series, and Chrysler Gen 3 Hemis.

Whether you are running high boost or a high compression naturally aspirated engines, EPX will
provide the detonation resistance that you need. Similar to Sunoco E85-R and Methanol; EPX
contains so much oxygen that it can't be rated with a typical octane test to determine the
rating. However, in real-world applications, Sunoco EPX provides protection to engines running up to 30
PSI of boost. Sunoco EPX was engineered with extreme performance in mind and can be the
solution to get your engine to the next level of performance.

SUNOCO TECH CORNER

Sunoco’s oxygenated fuels contain alcohol, and that alcohol helps performance. Alcohol can have some drawbacks, though: Proper storage becomes key when you’re talking about fuels containing alcohol. Alcohol is also such an effective cleaner that it could loosen deposits in older, dirtier systems and clog the fuel filter.
