Engine Oil Requirements
The vehicle's engine requires oil meeting GM Standard GM6094M. Use only an oil that meets GM Standard GM6094M. GM Goodwrench® oil meets all the requirements.
The viscosity chart shows, SAE 5W-30 is best for the vehicle. However, if the temperature will be 0°F (-18°C) or above and SAE 5W-30 is not available, you may use SAE 10W-30.
These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.
Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).
You should look for this information on the oil container, and use those oils that are identified as meeting GM Standard GM6094M and have the starburst symbol on the front of the oil container.
If you are in an area of extreme cold, where the temperature falls below -20°F (-29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures.
When the CHANGE ENGINE OIL light comes on, service is required for the vehicle. On vehicles driven under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However the engine oil and filter must be changed at least once a year and at this time the system must be reset.
If the engine oil life system is ever reset accidentally, the customer must have the vehicle serviced within 5 000 km (3,000 mi) since your last service. Reset the oil life system whenever you change the oil. Refer to GM Oil Life System - Resetting for information on the engine Oil Life System and resetting the system.
