280 DRIVING AND OPERATING
If unavailable, unleaded gasoline with
a posted octane rating of 87 may be
used, but will result in reduced
performance and driveability. If heavy
knocking is heard when using gasoline
rated at 91 or greater, the engine
needs service.
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Recommended Fuel (3.6L
V6 Engine)
Regular unleaded gasoline meeting
ASTM specification D4814 with a
posted octane rating (R+M)/2 of 87 or
greater is recommended. Do not use
gasoline with a posted octane rating
of less than 87, as this will result in
reduced performance and driveability.If heavy knocking is heard when using
gasoline rated at 87 or greater, the
engine needs service.
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
.For vehicles that are not
FlexFuel, fuel labeled greater
than 15% ethanol by volume,
such as mid-level ethanol blends
(16–50% ethanol), E85,
or FlexFuel.
.Fuel with any amount of
methanol, methylal, ferrocene,
and aniline. These fuels can
corrode metal fuel system parts
or damage plastic and rubber
parts.
(Continued)
Caution (Continued)
.Fuel containing metals such as
methylcyclopentadienyl
manganese tricarbonyl (MMT),
which can damage the emissions
control system and spark plugs.
.Fuel with a posted octane rating
of less than the recommended
fuel. Using this fuel will lower
fuel economy and performance,
and may decrease the life of the
emissions catalyst.
Fuels in Foreign Countries
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock index
(AKI). For fuel not to use in a foreign
country, seeProhibited Fuels 0280.

nozzle is inserted too quickly.
This spray can happen if the
tank is nearly full, and is more
likely in hot weather. Insert the
fill nozzle slowly and wait for any
hiss noise to stop before
beginning to flow fuel.
If equipped, the fuel door unlocks
when the vehicle doors are unlocked.

than three clicks of a standard fill
nozzle may cause:
.Vehicle performance issues,
including engine stalling and
damage to the fuel system.
.Fuel spills.
