E85 'flex-fuel' offers cheaper alternative
Posted: 1/14/2012

Do You Have a Flex-Fuel Vehicle?

Flexible fuel vehicles (FFVs) are designed to run on gasoline or a blend of up to 85% ethanol (E85). Except for a few engine and fuel system modifications, they are identical to gasoline-only models. FFVs experience no loss in performance when operating on E85 and you can use a mixture of both fuels.

Typically E85 is cheaper than gas... prices can vary greatly across the United States.

Look for the Yellow Gas Cap; Most manufacturers started putting yellow gas caps on FFVs as of model year 2008.
