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.
