Fluid and Lubricant Recommendations

Usage Fluid/Lubricant
Engine Oil Use only engine oil licensed to the dexos™ 1 specification or equivalent, of the proper SAE viscosity grade. ACDelco dexos™ 1 Synthetic Blend is recommended. Use SAE 5W-30 viscosity grade engine oil.
Cold Temperature Operation: In an area of extreme cold, where the temperature falls below -29°C (-20°F), an SAE 0W-30 oil may 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 of the correct specification. Refer to Owner's Manual for more information.
