A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.
Almost all gasoline now has some ethanol in it. Our Exxon and Mobil branded gasoline currently contains up to 10%. Gasoline with 10% ethanol content is known as E10, and with 15% ethanol itâs known as E15. Ethanol flex fuel (formerly known as E85) has between 51 and 83% ethanol with the remainder being gasoline. E15 is only appropriate for use in Flex Fuel vehicles or a very small percentage of the newest vehicles. Anything higher than E15 ethanol content is only appropriate in Flex Fuel vehicles.
