SERVICING AND MAINTENANCE 303
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed.
Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number should not be used.
Materials Added To Engine Oil
FCA strongly recommends against the addition
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
Filters
Care 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
an 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 with a
new filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be
used for replacement. The quality of
replacement filters varies considerably. Only
high quality Mopar certified filters should be
used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals
Ú page 297.
NOTE:
Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement filters varies
considerably. Only high quality Mopar certified
filters should be used.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air
conditioner should be checked and serviced by
an authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt tension should also be checked at
this time.
CAUTION!
Do not use chemical flushes in your engine oil
as the chemicals can damage your engine.
Such damage is not covered by the New Vehi-
cle Limited Warranty.
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 sys-
tem (air cleaner, hoses, etc.) removed. Failure
to do so can result in serious personal injury.
