Note:Your warranty will not cover anyvehicle damage, loss of vehicle performanceor repairs to your vehicle caused by the useof fuel not recommended.
Choosing the Right Fuel
Use only unleaded gasoline or unleadedgasoline blended with a maximum of 15%ethanol in your gasoline vehicle. If yourvehicle is a flex fuel vehicle (FFV), it willhave a yellow cap.
Do not use:
•Fuels containing more than 15%ethanol or E-85 fuel.
•Fuels containing methanol.
•Fuels containing metallic basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Prohibited by law, you cannot useleaded fuel.
Diesel Engine
Refer to the diesel supplement forinformation regarding diesel fuelrecommendations and requirements ofyour diesel-powered truck.
Choosing the Right Fuel With aFlex Fuel Vehicle (If Equipped)
Note:Flex fuel vehicles will have a yellowfuel cap.
Use only unleaded gasoline or unleadedgasoline 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 basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Prohibited by law, you cannot useleaded fuel.
Your warranty will not cover any vehicledamage, loss of vehicle performance orrepairs to your vehicle, caused by the useof fuel not recommended.
It is best not to alternate repeatedlybetween gasoline and E85. If you do switchfuels, it is recommended that you add asmuch fuel as possible—at least half a tank.Do not add less than 5.0 gal (18.9 L)whenrefueling. You should drive the vehicleimmediately after refueling for at least5.0 mi (8 km)to allow the vehicle to adaptto the change in ethanol concentration.The recommendation if you exclusively useE85 fuel, is to fill the fuel tank with regularunleaded gasoline at each scheduled oilchange.

Contamination with dirt, water,petroleum products or other materials may result in brake system damage and possiblefailure.3Add the coolant type originally equipped in your vehicle.4Ford has designed your engine to use Motorcraft engine oils or equivalent oils that meetFord’s specification. It is also acceptable to use an engine oil of recommended viscositygrade that meets API SN requirements and displays the API Certification Mark for gasolineengines.5Do not use oils labeled as API SN unless the label also display the API certification mark.These oils do not meet the requirements of your vehicles engine and emissions system.6Do not use supplemental engine oil additives.

Some applications may vary based on coolersize and if equipped with an in-tank cooler. You should set the amount of transmissionfluid and fluid level by the indication on the dipstick’s normal operating range.9Fill to the proper capacity according to dipstick Type A. For correct dipstick type, SeeAutomatic Transmission Fluid Check (page 231).9Fill to the proper capacity according to dipstick Type B. For correct dipstick type, SeeAutomatic Transmission Fluid Check (page 231).10See the Warning below:
