FUEL QUALITY - GASOLINE
Choosing the Right Fuel
We recommend regular unleaded gasoline
with a pump (R+M)/2 octane rating of 87.
Some fuel stations offer fuels posted as
regular unleaded gasoline with an octane
rating below 87, particularly in high altitude
areas. We do not recommend fuels with
an octane rating below 87.
For vehicles with EcoBoost engines, to
provide improved performance, we
recommend premium fuel for severe duty
usage such as trailer tow.
Do not use any fuel other than those
recommended because they could lead to
engine damage that may not be covered
by the vehicle Warranty.
Note:
Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 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 (using leaded fuel is
prohibited by law).
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you have run out of fuel:
• You may need to cycle the ignition from
off to on several times after refueling
to allow the fuel system to pump the
fuel from the tank to the engine. On
restarting, cranking time will take a few
seconds longer than normal. With
keyless ignition, just start the engine.
Crank time will be longer than usual.
• Normally, adding 1 gallon (4.6 liters) of
fuel is enough to restart the engine. If
your vehicle is out of fuel and on a
steep grade, more than 1 gallon (4.6
liters) may be required.
