FUEL QUALITY
Choosing the Right Fuel
Use only regular unleaded gasoline with a
minmum 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. Fuels with octane levels
below 87 are not recommended.
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 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.
