API SERVICE GRADE CERTIFIED

Engine Oil Container Standard Notations:





In gasoline engines, use an engine oil that is API Service Grade Certified. 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. MOPAR(R) only provides engine oil that conforms to this certification.

SAE VISCOSITY

Temperature/Engine Oil Viscosity Recommendation:





An SAE viscosity grade is used to specify the viscosity of engine oil. SAE BOW-30 specifies a multiple viscosity engine oil. These are specified with a dual SAE viscosity grade which indicates the cold-to-hot temperature viscosity range. When choosing an engine oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Select an engine oil that is best suited to your area's particular ambient temperature range and variation.

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.
