Fuel Quality - Ford SUPER DUTY Owner's Manual

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.
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 bezel placed
over the fuel fill inlet.
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).
• Leaded-fuel (The use of leaded fuel is
prohibited by law).
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)

The use of any fuel other than the
recommended fuel can cause powertrain
damage, impair the emission control
system or cause loss of vehicle
performance will not be covered under
warranty.
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.
