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.
FUEL QUALITY - E85
Choosing the Right Fuel - Flex Fuel
Vehicles Use regular unleaded gasoline with a
minimum pump (R+M)/2 octane rating of
87, or regular unleaded gasoline blended
with a maximum of 85% ethanol (E85).
Flex fuel vehicles have a yellow fuel filler
cap or the fuel tank filler pipe will have a
yellow housing or bezel. Some fuel stations
offer fuels posted as regular unleaded
gasoline with an octane rating below 87,
particularly in high altitude areas. Fuels
with octane levels below 87 are not
recommended.

Fuel Requirements - Choosing the
Right Fuel: Vehicles Operated
Where Ultra-Low Sulfur Diesel Fuel
is Required (United
States/Canada/Puerto Rico/U.S.
Virgin Islands and Other Locales) WARNINGS
Only use Ultra-Low Sulfur Diesel fuel
(ULSD) containing a maximum of 15
ppm sulfur and up to 20% biodiesel
(B20). These fuels should meet the diesel
specifications defined by American Society
for Testing and Materials (ASTM) D975 for
diesel and by ASTM D7467 for B6-B20
blends, or an equivalent local market
specification. Do not mix diesel with oil, kerosene,
paraffin, gasoline or other liquids to
diesel. This can cause damage to the
fuel system. Do not use home heating oil,
agricultural fuel, raw fats, oils, waste
cooking greases, biodiesel fuels
greater than 20% or any diesel fuel not
intended for highway use. The vehicle warranty will not cover
damage caused by using an improper
type of fuel or fuel additive.
Note:
Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel will
significantly increase your vehicle ’s exhaust
emissions and reduce engine life due to
increased internal wear.
