Many Cars Already Run on E10!


E85E10 is a blend of ethanol and gasoline which contains 10% ethanol + 90% gasoline. All new cars sold in the U.S. since 1986 are capable of running on E10. Higher blends, such as E15 and E20, are also being studied to determine whether they can be used in all vehicles capable of running on gasoline (DOE EERE, 2009).

Flexible Fuel Vehicles (FFV) are capable on running on any blend of gasoline and ethanol from:

100% gasoline + 0% ethanol (conventional gasoline)


15% gasoline + 85% ethanol (E85) (EPA, 2009)

You must have a FFV to drive on higher blends of gasoline and ethanol such as E85!
