•
Fuels can also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and wash
skin thoroughly with soap and water.
Repeated or prolonged skin contact with
fuel liquid or vapor causes skin irritation.
• Be particularly careful if you are taking
“Antabuse ” or other forms of disulfiram
for the treatment of alcoholism. Breathing
gasoline vapors, or skin contact could
cause an adverse reaction. In sensitive
individuals, serious personal injury or
sickness may result. If fuel is splashed on
the skin, promptly wash skin thoroughly
with soap and water. Consult a physician
immediately if you experience an adverse
reaction.
FUEL QUALITY
We recommend that you use only high
quality fuel without additives or other engine
treatments. Choosing the Right Fuel
Use only UNLEADED gasoline or UNLEADED
gasoline blended with a maximum of 15%
ethanol in your gasoline vehicle.
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 your vehicle that is caused by
use of fuel not recommended will not be
covered under warranty. Octane Recommendations
2.0L EcoBoost Engine
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.
Premium fuel will provide improved
performance and is recommended for severe
duty usage.
3.7L Engine
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.

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.
Note: Automatic transmissions that require
MERCON LV transmission fluid should only
use MERCON LV transmission fluid. The use
of any other fluid may cause transmission
damage.
