Fuel Quality; Octane Recommendations - Ford 2015 F-150 Owner's Manual

FUEL QUALITY

Choosing the Right Fuel Without
a Flex Fuel Vehicle (If Equipped)
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), the fuel fill inlet will have a yellow
housing.
Do not use:
• Fuel containing more than 15% ethanol
or E-85 fuel.
• Fuel with 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).
Note: Use of any fuel other than
recommended fuel can cause powertrain
damage, impair the emission control system
or cause loss of vehicle performance. Any
damage to vehicle that is caused by use of
fuel not recommended will not be covered
under warranty.

Octane Recommendations

E161513
Do not be concerned if the engine
sometimes knocks lightly. However, if it
knocks heavily under most driving
conditions while you are using fuel with the
recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
2.7L and 3.5L EcoBoost Engines
We recommend regular unleaded gasoline
with a pump (R+M)/2 octane rating of 87.
Some stations offer fuels posted as regular
with an octane rating below 87, particularly
in high altitude areas. We do not
recommend fuels with an octane rating
below 87.
To provide improved performance, we
recommend premium fuel for severe duty
usage, such as trailer tow.
