Materials Added To Engine Oil
The manufacturer 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
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 section
for the proper maintenance intervals.
