E10 for all Vehicles
E10 (10% ethanol and 90% unleaded gasoline) is approved for use in any make or model vehicle sold in the U.S. Many automakers recommend its use because of its high-performance, clean-burning characteristics. It is important to note it does not take a special vehicle to run on ethanol. All vehicles are “ethanol vehicles” and can use up to 10% ethanol with no modifications to the engine.
Mid-Range Blends: E20 and E30
The American Coalition for Ethanol (ACE) is leading efforts to attend to any hurdles for using ethanol blends above 10%, such as E20 and E30. If these higher percentages could be used in standard vehicles, the U.S. could significantly decrease our dependence on petroleum from foreign countries. New research shows that mid-range ethanol blends can in some cases provide better fuel economy than regular unleaded gasoline — even in standard, non-flex-fuel vehicles. Research suggests there is an “optimal blend level” of ethanol and gasoline (most likely E20 or E30) at which vehicles get better gas mileage than predicted.

E85 for Flex-Fuel Vehicles
E85 is an alternative fuel for use in flexible fuel vehicles (FFV). There are currently more than 6 million FFVs on Americas roads with more coming each month. In conjunction with more flex-fuel vehicles, more E85 pumps are being installed across the country.
