API SERVICE GRADE CERTIFIED
Use an engine oil that is API Service Grade Certified. MOPAR provides engine oils that conform to this service grade.
SAE VISCOSITY
An SAE viscosity grade is used to specify the viscosity of engine oil. Use only engine oils with multiple viscosities such as 5W-30 or 10W-30 in the
4.7L engines. The 4.7L H.O uses 10W-30 oil only. These are specified with a dual SAE viscosity grade, which indicates the cold-to-hot temperature
viscosity range. Select an engine oil that is best suited to your particular temperature range and variation (Fig. 90).
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY CONSERVING is located on the label of an
engine oil container.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have been adopted to aid in the proper selection of engine oil. The identifying notations are located on the
label of engine oil plastic bottles and the top of engine oil cans (Fig. 91).
