Engine Oil

SAE GRADE RATING INDICATES ENGINE OIL VISCOSITY
An SAE viscosity grade is used to specify the viscosity of engine oil. SAE 30 specifies a single viscosity engine oil. Engine oils also have multiple viscosities. These are specified with a dual SAE viscosity grade which indicates the cold-to-hot temperature 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 performance the engine oil is intended to provide. The API Service Grade specifications also apply to energy conserving engine oils.

Use engine oils that are API Service Certified. 5W-30 and 10W-30 MOPAR engine oils conform to specifications.
