230 Driving and Operating
Do not use gasoline with a posted octane
rating of less than 87, as this may cause
engine knock and will lower fuel economy.
Do not use any fuel labeled E85 or FlexFuel.
Do not use gasoline with ethanol levels
greater than 15% by volume.
Recommended Fuel (2.0L L4 Turbo
Engine and 6.2L V8 Engine)
Premium unleaded gasoline meeting ASTM
specification D4814 with a posted octane
rating of 93—(R+M)/2 —is highly
recommended for best performance and fuel
economy. Unleaded gasoline with an octane
rated as low as 87 can be used. Using
unleaded gasoline rated below 93 octane,
however, will lead to reduced acceleration
and fuel economy. If knocking occurs, use a
gasoline rated at 93 octane as soon as
possible, otherwise, the engine could be
damaged. If heavy knocking is heard when
using gasoline with a 93 octane rating, 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 (6.2L V8
Supercharged Engine)
Use premium unleaded gasoline meeting
ASTM specification D4814 with a posted
octane rating of 93
—(R+M)/2.
If unavailable, unleaded gasoline with a
posted octane rating of 91 may be used, but
with reduced performance and fuel
economy. If the octane is less than 91, the
engine could be damaged and the repairs
would not be covered by the vehicle
warranty. If heavy knocking is heard when
using gasoline rated at 93 octane, 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.
.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.
