Oil Change
The engine oil filter should be replaced with a new filter at every engine oil change. This 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. MOPAR engine oil filters are a high quality oil filter and are recommended.
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 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.
