250 SERVICING AND MAINTENANCE
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its perfor -
mance 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, indiscrimi -
nately discarded, can present a problem to the environment.
Contact an authorized dealer, service station or govern -
mental 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

This manufacturer's engines have a full-flow type disposable 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 ensure most efficient service. Mopar engine
oil filters are high quality oil filters and are recommended.

Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this chapter for the
proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions” maintenance
interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
ensure most efficient service. Mopar engine air cleaner filters
are a high quality filter and are recommended.
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.
