Section
4
Use of the recommended fuel is
an important part of the proper
maintenance of your vehicle.
You should use a high quality fuel
which meets the minimum octane
rating recommended.
Use gasoline with a posted octane
of 95 (research method) or higher.
A gasoline with posted octane of
91 or higher can also be used, but
the vehicle's acceleration may be
slightly reduced.
Note:
You may use either regular
unleaded gasoline or ethanol
fuel up to 85% (E-85).
See "Ethanol (E-85) Fuel"
later in this section for more
information.
The use of gasoline with an
octane rating lower than that
recommended may cause engine
knock. Continued use can cause
engine damage and void the
warranty.
If you detect a heavy engine knock
even when using a gasoline of the
recommended octane rating, have
the engine checked. Short periods
of engine knock during hill
climbing and acceleration are
acceptable.
Ethanol (E-85) Fuel
NOTICE
Do not use methanol.
Your vehicle was not designed
for fuels that contain methanol.
Methanol can corrode metal
parts in your fuel system and
can also damage plastic and
rubber parts. Damage caused
by the use of fuels that contain
methanol would not be
covered by your warranty.
