Maintenance and Specifications Cleaner air Ford endorses the use of reformulated "cleaner-burning" gasolines to improve air quality, per the recommendations in the Choosing the right fuel section. Octane recommendations Your vehicle is designed to use "Regular" unleaded gasoline with a pump (R+M)/2 octane rating of 87. Some stations offer fuels posted as "Regular" with an 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 (R+M)/2 METHOD using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage. 87 FFV engine (if equipped) If your vehicle is flex fuel capable, it is designed to use Fuel Ethanol (Ed75-Ed85), "Regular" unleaded gasoline or any mixture of the two fuels. Use of other fuels such as Fuel Methanol may cause powertrain damage, a loss of vehicle performance, and your warranty may be invalidated. 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 (18.9L) when refueling. You should drive the vehicle immediately after refueling for at least 5 miles (8 km) to allow the vehicle to adapt to the change in ethanol concentration. If you operate your vehicle 50% or more of the time on ethanol, you should follow a different maintenance schedule. In addition to this, if you exclusively use E85 fuel, it is also recommended to fill the fuel tank with regular unleaded gasoline once every 3,000 miles (4,800 km). See scheduled maintenance information for more information. Fuel quality Do not add aftermarket fuel additive products to your fuel tank. It should not be necessary to add any aftermarket products to your fuel tank if you continue to use high quality fuel of the recommended octane 256 2010 Town Car (tow) Owners Guide, 1st Printing USA (fus)
