Fuel and Refueling 153 FUEL QUALITY Note: Use of any fuel other than those recommended may cause powertrain damage and a loss of vehicle performance; repairs may not be covered under warranty. Choosing the Right Fuel Use only unleaded fuel or unleaded fuel blended with a maximum of 15% ethanol. Do not use fuel ethanol (E85), diesel fuel, fuel- methanol, leaded fuel or any other fuel because it could damage or impair the emission control system. Choosing the Right Fuel With a Flex Fuel Vehicle (If Equipped) Note: If your vehicle is flex fuel capable, it will have a yellow bezel placed over the fuel fill inlet. Flex fuel vehicles are designed to use unleaded gasoline or an ethanol fuel blend that contain up to 85% ethanol. It is also acceptable to use any mixture of unleaded gasoline and ethanol fuel that contains up to 85% ethanol. An ethanol fuel blend that contains 85% ethanol is labeled as E85 at the service station. It is best not to alternate repeatedly between gasoline and E85. If you do switch fuels, it is recommended that you add as much fuel as possible-at least half a tank. Do not add less than five gallons (18.9 liters) when refueling. You should drive the vehicle immediately after refueling for at least 5 miles (8 kilometers) to allow the vehicle to adapt to the change in ethanol concentration. If you exclusively use E85 fuel, it is recommended to fill the fuel tank with regular unleaded gasoline at each scheduled oil change. Octane Recommendations Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. Some stations offer fuels posted as "Regular" with an (R+M)/2 METHOD octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended. Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily under most driving conditions while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage. 87 2014 Focus (foc) Owners Guide gf, 1st Printing, October 2012 USA (fus)
