•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)

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.

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 240).9Fill to the proper capacity according to dipstick Type B.
