Sunoco E30-R 99 Octane Race Fuel

Sunoco E30-R 99 Octane Unleaded Racing Fuel contains 30% Ethanol. 

Sunoco E30-R is an advanced unleaded racing fuel containing 30% ethanol by volume. In cars that can take advantage of the higher oxygen and octane levels, Sunoco E30-R can be an effective tool for generating more power. This highly oxygenated fuel requires increased fuel flow compared to conventional fuels like pump gas. Check with your performance tuning shop to verify that your car’s fuel system can meet the increased fuel flow requirements to fully utilize the potential of Sunoco E30-R.

The recipe of Sunoco E30-R is held constant which provides a strong foundation for other performance modifications. Each batch is rigorously tested and certified to contain 30% ethanol by volume. The non-ethanol portion consists of highly refined race fuel hydrocarbons, ensuring superior stability and consistency. 

Sunoco E30-R is free of metallic additives and is safe for oxygen sensors and catalytic converters. For optimal shelf life, it should be stored in dark, tightly sealed containers where the temperature is stable. Under these conditions, its shelf life exceeds one year.

SUNOCO TECH CORNER

The amount of ethanol in E30-R is usually still supported by the stock fuel system in high performance vehicles, so it’s the most ethanol a car can handle before they need to start customizing it.

Sunoco's E30-R and EVO 10 have similar applications. While the EVO 10 has a higher octane rating which potentially is better from a performance standpoint, EVO 10 has a small amount of methanol and an additive called MMT. These would be considered “exotic” ingredients compared to E30-r being made strictly of high quality race gas and 30% ethanol. Some people don’t desire these exotic ingredients and E30-r is more palatable because they understand exactly what they are getting.

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.
