Usage

Fluid/Lubricant

Engine Oil

The engine requires a special engine oil meeting standard GM4718M. Oils meeting this standard can be identified as synthetic, and should also be identified with the American Petroleum Institute (API) Certified for Gasoline Engines starburst symbol. However, not all synthetic API oils with the starburst symbol will meet this standard. Look for and use only an oil that meets standard GM4718M. For the proper viscosity, see Engine Oil.
