ENGINE OIL QUALITY
Oils of the proper quality for the vehicle can be identified by looking for the STARBURST symbol. The STARBURST symbol indicates that the oil has been certified by the American Petroleum Institute (API), and is preferred for use in gasoline engines.

ENGINE OIL VISCOSITY






NOTICE: Using oils of any viscosity other than those recommended could result in engine damage. When choosing an oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Then, select the recommended oil viscosity.

SAE 5W-30 is the only viscosity grade recommended for your vehicle.
Use only oils which have the API Starburst symbol and which are also identified as SAE 5W-30.

If the temperature range is 0°F (-18°C) or above SAE 10W-30 oil which has the API Starbust symbol is acceptable if SAE 5W-30 oil is not available. Areas where the temperature falls below -20°F (-29°C), it is recommended either an SAE 5W-30 synthetic oil or and SAE 0W-30 oil. Both will provide easier cold starting and better protection for the engine at extremely low temperatures. Do not use other viscosity grade oils, such as SAE 10W-40 or SAE 20W-50 under any conditions.

ENGINE OIL ADDITIVES
Do NOT add engine oil additives. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all that is needed for good performance and engine protection.
