What Kind of Engine Oil to Use
Look for three things:

• GM6094M
Use only an oil that meets GM Standard GM6094M.
• SAE 5W-30
SAE 5W-30 is best for the vehicle. These numbers on an oil container show its viscosity, or thickness.
Do not use other viscosity oils such as SAE 20W-50.
• American Petroleum Institute (API) starburst symbol

Oils meeting these requirements should have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).
Notice: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by the vehicle warranty.
