Engine Oil



SAE 5W-20 and SAE 5W-30 engine oils are recommended for all operating temperatures. These engine oils are designed to improve low temperature starting and vehicle fuel economy. Refer to the engine oil filler cap for the preferred engine oil viscosity grade for each vehicle.

SAE viscosity grades are used to specify the correct viscosity oil for an engine. Use only Multi-Viscosity oils such as SAE 5W-20 or 5W-30. These are specified with a dual SAE viscosity grade which indicates the cold (5W) to hot (20, 30) temperature performance range of the oil.

Use an engine oil that is API Certified (API Certification Mark) and Licensed to display the certification mark. MOPAR provides engine oils that meet or exceed, Material Standard MS-6395 requirement.
