Maintenance and Specifications FFV engine (if equipped) Flexible fuel vehicle (FFV) fuel tanks may contain 0 to 85 percent or more of ethnanol. Any fuel blends containing gasoline and ethanol should be treated the same as "Fuel Ethanol (E85)." To identify if your vehicle is an FFV, check your VIN or the label on the inside of your fuel filler door. When checking your VIN, the engine type identifier (8th character) is "K." If you have a flex fuel vehicle, use only UNLEADED FUEL and ETHANOL (E85). Note: Flexible fuel components and standard unleaded fuel components are NOT interchangeable. If your vehicle is not serviced in accordance with flexible fuel vehicle procedures, damage may occur and your warranty may be invalidated. U.S. government regulations require fuel ethanol dispensing pumps to have a small, square, orange and black label with the common abbreviation E85 or the appropriate percentage for that region. Use of other fuels such as Fuel Methanol may cause power train damage, a loss of vehicle performance, and your warranty may be invalidated. Fuel quality The World-wide Fuel Charter recommends gasoline specifications to provide improved performance and emission control system protection. Ask your fuel supplier about gasolines that meet the World-wide Fuel Charter. In Canada, look for fuels that display the Auto Makers' Choice logo. It should not be necessary to add any aftermarket products to your fuel tank if you use high quality fuel of the recommended octane rating. Aftermarket products could cause damage to the fuel system and invalidate your warranty. Cleaner air Ford endorses the use of reformulated "cleaner-burning" gasolines to improve air quality. 153
