.
Synthetic engine oils which do not have both the engine oil
certifi
cation mark and the correct SAE viscosity grade

Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
e
ngine o
il. 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
f
ilters
from your vehicle. Used oil and oil filters, indiscrimi-
nately discarded, can present a problem to the environment.
C
ontact
an authorized dealer, service station or govern-
mental agency for advice on how and where used oil and oil
f
ilters
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
f
ilter.
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 high quality oil filters and are recommended.
