FUEL QUALITY
Choosing the Right Fuel
Use premium unleaded gasoline with a
minimum 91 octane rating using the
(R+M/2 method).
Ford Performance recommends using
unleaded gasoline with octane rating of
93 or higher for optimal performance of
this vehicle.
Recommended fuel is an important part
of the proper maintenance and optimal
performance of your vehicle. The use of
gasoline with an octane rating lower than
91 can lead to severe mechanical damage.
This may also degrade vehicle
performance and 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).

Fuel and Refueling
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 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.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is located in the
storage compartment under the rear hatch.
RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
•
•
92
Add a minimum of 1.3 gal (5 L) of fuel
to restart the engine. If your vehicle is
out of fuel and on a steep slope, more
fuel may be required.
You may need to switch 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. When restarting, cranking time
takes a few seconds longer than
normal.
