FUEL QUALITY - GASOLINE
Choosing the Right Fuel
E161513
We recommend regular unleaded gasoline
with a pump 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 unleaded gasoline will provide
improved performance and is
recommended for severe duty usage, for
example a fully loaded vehicle.
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.
• Kerosene or paraffin fuels.
• Fuel containing more than 15% ethanol
or E-85 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 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.
