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.
E85 Ethanol Flexible-Fuel Vehicles and B20 Biofuel Vehicles. Every Ford flexible-fuel vehicle (FFV) is engineered to run on E85 (85% ethanol and 15% gasoline), unleaded gasoline or any blend of the two. Several Ford trucks can operate on any blend of up to 20% biodiesel and 80% petroleum diesel (a mix known as B20) Both biodiesel and ethanol are cleaner burning and more renewable than conventional fuels.
