Selecting the Right Engine Oil
Selecting the right engine oil depends on both the proper oil specification and viscosity grade.
See Recommended Fluids and Lubricants.
Specification
Use and ask for licensed engine oils with the dexos1™ approved certification mark. Engine oils meeting the requirements for the vehicle should have the dexos1 approved certification mark.
This certification mark indicates that the oil has been approved to the dexos1 specification.
Notice: Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Check with your dealer or service provider on whether the oil is approved to the dexos1 specification.
Viscosity Grade
SAE 5W—30 is the best viscosity grade for the vehicle. Do not use other viscosity grade oils such as SAE 10W—30, 10W—40, or 20W—50.
If in an area of extreme cold, where the temperature falls below −20°F (−29°C), an SAE 0W—30 oil should be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.
When selecting an oil of the appropriate viscosity grade, always select an oil that meets the dexos1 specification or equivalent. See “Specification” for more information.
