You should look for this information on the oil container, and use only those oils that are identified as meeting standard GM6094M and have the starburst symbol on the front of the oil container. Notice: Use only engine oil identified as meeting 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 your warranty. 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 the engine at extremely low temperatures. Engine Oil Additives Do not add anything to the oil. The recommended oils with the starburst symbol that meet standard GM6094M are all you will need for good performance and engine protection. Engine Oil Life System When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. 337
