LUBRICATION &
MAINTENANCE

DESCRIPTION - FUEL REQUIREMENTS

Your engine is designed to meet all emissions reg-

ulations and provide excellent fuel economy and per-
formance when using high quality unleaded “regular”
gasoline having an octane rating of 87. The routine
use of premium gasoline is not recommended. Under
normal conditions the use of premium fuel will not
provide a benefit over high quality regular gasolines
and in some circumstances may result in poorer per-
formance.

Light spark knock at low engine speeds is not

harmful to your engine. However, continued heavy
spark knock at high speeds can cause damage and
immediate service is required. Engine damage result-
ing from operation with a heavy spark knock may
not be covered by the new vehicle warranty.

Poor quality gasoline can cause problems such as

hard starting, stalling and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.

Over 40 auto manufacturers world-wide have

issued and endorsed consistent gasoline specifications
(the Worldwide Fuel Charter, WWFC) to define fuel
properties necessary to deliver enhanced emissions,
performance and durability for your vehicle. We rec-
ommend the use of gasolines that meet the WWFC
specifications if they are available.

REFORMULATED GASOLINE

Many areas of the country require the use of

cleaner burning gasoline referred to as “reformulat-
ed” gasoline. Reformulated gasoline contain oxygen-
ates, and are specifically blended to reduce vehicle
emissions and improve air quality.

We strongly support the use of reformulated gaso-

line. Properly blended reformulated gasoline will pro-
vide excellent performance and durability for the
engine and fuel system components.

GASOLINE/OXYGENATE BLENDS

Some fuel suppliers blend unleaded gasoline with

oxygenates such as 10% ethanol, MTBE, and ETBE.
Oxygenates are required in some areas of the country
during the winter months to reduce carbon monoxide
emissions. Fuels blended with these oxygenates may
be used in your vehicle.

CAUTION: DO NOT use gasoline containing METH-
ANOL. Gasoline containing methanol may damage
critical fuel system components.

MMT IN GASOLINE

MMT is a manganese-containing metallic additive

that is blended into some gasoline to increase octane.
Gasoline blended with MMT provide no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT reduce
spark plug life and reduce emission system perfor-
mance in some vehicles. We recommend that gasolines
free of MMT be used in your vehicle. The MMT con-
tent of gasoline may not be indicated on the gasoline
pump; therefore, you should ask your gasoline retailer
whether or not his/her gasoline contains MMT.

It is even more important to look for gasoline with-

out MMT in Canada because MMT can be used at
levels higher than allowed in the United States.
MMT is prohibited in Federal and California refor-
mulated gasoline.

SULFUR IN GASOLINE

If you live in the northeast United States, your vehi-

cle may have been designed to meet California low
emission standards with Cleaner-Burning California
reformulated gasoline with low sulfur. If such fuels are
not available in states adopting California emission
standards, your vehicles will operate satisfactorily on
fuels meeting federal specifications, but emission con-
trol system performance may be adversely affected.
Gasoline sold outside of California is permitted to have
higher sulfur levels which may affect the performance
of the vehicle’s catalytic converter. This may cause the

Malfunction Indicator Lamp (MIL), Check Engine or
Service Engine Soon light to illuminate. We recom-
mend that you try a different brand of unleaded gaso-
line having lower sulfur to determine if the problem is
fuel related prior to returning your vehicle to an
authorized dealer for service.

CAUTION: If the Malfunction Indicator Lamp (MIL),
Check Engine or Service Engine Soon light is flash-
ing, immediate service is required; see on-board
diagnostics system section.

MATERIALS ADDED TO FUEL

All gasoline sold in the United States and Canada

are required to contain effective detergent additives.
Use of additional detergents or other additives is not
needed under normal conditions.

FUEL SYSTEM CAUTIONS

CAUTION: Follow these guidelines to maintain your
vehicle’s performance:

• The use of leaded gas is prohibited by Federal

law. Using leaded gasoline can impair engine perfor-
mance, damage the emission control system, and
could result in loss of warranty coverage.

• An out-of-tune engine, or certain fuel or ignition

malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.

• When pulling a heavy load or driving a fully

loaded vehicle when the humidity is low and the tem-
perature is high, use a premium unleaded fuel to
help prevent spark knock. If spark knock persists,
lighten the load, or engine piston damage may result.

• The use of fuel additives which are now being

sold as octane enhancers is not recommended. Most
of these products contain high concentrations of
methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such fuels
or

additives

not

responsibility

DaimlerChrysler Corporation and may not be covered
under the new vehicle warranty.

NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
