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: Your warranty will not cover any
vehicle damage, loss of vehicle performance
or repairs to your vehicle caused by the use
of fuel not recommended.
Choosing the Right Fuel
Use only unleaded gasoline or unleaded
gasoline blended with a maximum of 15%
ethanol in your gasoline vehicle. If your
vehicle is a flex fuel vehicle (FFV), it will
have a yellow cap.
Do not use:
• Fuels containing more than 15%
ethanol or E-85 fuel.
• Fuels containing methanol.
• Fuels containing metallic based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Prohibited by law, you cannot use
leaded fuel.
Diesel Engine
Refer to the diesel supplement for
information regarding diesel fuel
recommendations and requirements of
your diesel-powered truck.
Choosing the Right Fuel With a
Flex Fuel Vehicle (If Equipped)
Note: Flex fuel vehicles will have a yellow
fuel cap. 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).
• Prohibited by law, you cannot use
leaded fuel.
Your warranty will not cover any vehicle
damage, loss of vehicle performance or
repairs to your vehicle, caused by the use
of fuel not recommended.
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 5.0 gal (18.9 L)when
refueling. You should drive the vehicle
immediately after refueling for at least
5.0 mi (8 km)to allow the vehicle to adapt
to the change in ethanol concentration.
The recommendation if you exclusively use
E85 fuel, is to fill the fuel tank with regular
unleaded gasoline at each scheduled oil
change.
