• Prolonged idling (such as, vehicle operation in stop
and go traffic).
• Frequent short running periods. Not allowing en-
gine to warm to operating temperatures.
• Police or taxi usage.

API QUALITY CLASSIFICATION.
• SG service engine oil is a high quality crankcase
lubricant designed for use in all naturally aspirated
engines.
• SG/CD service engine oil is a high performance
crankcase lubricant designed for use in all gasoline or
diesel engines.
GEAR LUBRICANTS
SAE ratings also apply to multiple grade gear lubri-
cants. In addition, API classification defines the lubri-
cants usage.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage by
the NLGI. All approved products have the NLGI sym-
bol on the label.
At the bottom NLGI symbol is the usage and qual-
ity identification letters. Wheel bearing lubricant is
identified by the letter ''G''. Chassis lubricant is iden-
tified by the letter ''L''. The letter following the usage
letter indicates the quality of the lubricant. The fol-
lowing symbols indicate the highest quality.
PARTS REQUIRING NO LUBRICATION
Many components on a Chrysler Corporation ve-
hicle require no periodic maintenance. Some compo-
nents are sealed and permanently lubricated. Rubber
bushings can deteriorate or limit damping ability if
lubricated. The following list of components require
no lubrication:
