E85 Fuel

E85 is a blend of gasoline and denatured ethanol containing up to 85 percent ethanol and is the highest ethanol fuel blend available in the market. E85 can only be used in flex fuel vehicles (FFVs) which are specifically designed to run on this fuel or any gasoline or ethanol blend ranging from E0 to E85. Much like diesel fuel, E85 is available at specially-marked fueling pumps.

Expanding use of E85 as a vehicle fuel would increase use of renewable fuel and reduce dependence on imported oil. E85 can also provide important reductions in greenhouse gas (GHG) emissions as compared to petroleum-derived gasoline or lower volume ethanol blends.
