Fuel and Refueling FUEL QUALITY Note: Do not add after-market fuel additive products to your fuel tank. We recommend that you use only high quality fuel without after-market additives or other engine treatments. Note: Use of any fuel other than those recommended may cause powertrain damage, a loss of vehicle performance, and repairs may not be covered under warranty. Use only UNLEADED gasoline or UNLEADED gasoline blended with a maximum of 85% ethanol (E-85) in your Flex Fuel Vehicle (FFV). Do not use Fuels containing more than 85% ethanol or E-100 fuel. Fuels containing methanol. Fuels containing metallic based additives, including manganese-based compounds. Fuels containing the octane booster additive, methylcyclopentadienyl manganese tricarbonyl (MMT). Leaded-fuel (The use of leaded fuel is prohibited by law).

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 5.0 mph (8 km/h) 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. • • Diesel Engine Refer to the diesel supplement for information regarding diesel fuel recommendations and requirements of your diesel-powered truck.
