FUEL QUALITY
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:
•
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 Do not be concerned if your engine
sometimes knocks lightly. However, if it
knocks heavily under most driving
conditions while you are using fuel with the
recommended octane rating, see your
authorized dealer to prevent any engine
damage.
2.3L EcoBoost and 5.0L V8 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.
3.7L V6 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.
RUNNING OUT OF FUEL
Avoid running out of fuel. This situation
may have an adverse effect on powertrain
components.
If you have run out of fuel:

1 For complete refill of limited slip Ford axles, add 4 oz. (118 ml) of Additive Friction Modifier
XL-3 or equivalent meeting Ford Specification EST-M2C118-A. Ford rear axles contain a
synthetic lubricant that does not require changing unless you submerge the axle in water.
If you use oil and fluids that do not meet
the defined specification and viscosity
grade, this may lead to:
• Component damage which is not
covered by the vehicle warranty.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Degraded brake performance.
Use of synthetic or synthetic blend motor
oil is not mandatory. Only use fluid that
meets Ford specifications. Motor oils of
the recommended viscosity grade that
meet API SN requirements and display the
API Certification Mark for gasoline engines
are also acceptable. Do not use oil labeled
with API SN service category unless the
label also displays the API certification
mark. An oil that displays this symbol conforms
to current engine, emission system and
fuel economy performance standards of
the International Lubricant Standardization
and Approval Committee (ILSAC).
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by your vehicle warranty.
Note:
Ford recommends using DOT 4 Low
Viscosity (LV) High Performance Brake Fluid
or equivalent meeting WSS-M6C65-A2. Use
of any fluid other than the recommended
fluid may cause degraded brake
performance and not meet the Ford
performance standards. Keep brake fluid
clean and dry. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage and possible failure.
