FUEL QUALITY
Choosing the Right Fuel
E161513E161513
Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in high
altitude areas, offer fuels posted as regular
unleaded gasoline with an octane rating
below 87. The use of these fuels could result
in engine damage that is not covered by the
vehicle warranty.For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well as
other conditions, for example when towing
a trailer. See Towing (page 354).
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.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal vehicle
and engine performance. For additional
information, refer to www.toptiergas.com.
Note:Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.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 additives impair
engine performance and affect the emission
control system.
