ENGINE OIL
SAE GRADE RATING INDICATES ENGINE OIL VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. SAE 30 specifies a single viscos-
ity
engine
oil.
Engine
oils
also
have
multiple
viscosities. These are specified with a dual SAE vis-
cosity grade which indicates the cold-to-hot tempera-
ture viscosity range.
• SAE 30 = single grade engine oil.
• SAE 10W-30 = multiple grade engine oil.
API QUALITY CLASSIFICATION
The API Service Grade specifies the type of perfor-
mance the engine oil is intended to provide. The API
Service Grade specifications also apply to energy con-
serving engine oils.
Use engine oil that is API Service Grade Certified
or an oil that conforms to the API Service Grade SH
or SH/CD. MOPAR engine oils conform to all of these
service grades.
Refer to Group 9, Engine for engine oil specifica-
tion.
GEAR LUBRICANTS
SAE ratings also apply to multiple grade gear
lubricants. In addition, API classification defines the
lubricants usage.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 3) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
“G”. Chassis lubricant is identified by the latter “L”.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.
