Engine Oil Viscosity (SAE Grade) — 3.3L & 3.8L
Gasoline EnginesSAE 5W-20
engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
“Engine Compartment” in this section.
Lubricants that do not have both the engine oil certifica-
tion mark and the correct SAE viscosity grade number,
should not be used.
Engine Oil Viscosity (SAE Grade) — 4.0L Gasoline
Engines
SAE 10W-30 engine oil is preferred for all operating
temperatures. Your engine oil filler cap also shows the
recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, refer to
“Engine Compartment” in this section.
Lubricants that do not have both the engine oil certifica-
tion mark and the correct SAE viscosity grade number,
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental
additives.

Disposing of Used Engine Oil and Oil FiltersCare should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. MOPARt
engine oil filters are a high quality oil
filter and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals. WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
442 MAINTAINING YOUR VEHICLE

used to assure most efficient service. MOPARtengine air
cleaner filters are a high quality filter and are
recommended.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required. WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Exhaust Gas” in the Safety Tips section of this
manual.
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
