Engine Oil (Gasoline Engine -- except Cadillacs and 6.0L V8 Trailblazer)

Engine oil which meets GM Standard GM6094M and displays the American Petroleum Institute Certified for Gasoline Engines starburst symbol. To determine the proper viscosity for your vehicle's engine, see "Engine Oil" in your owner manual.

Engine Oil (Cadillacs and 6.0L V8 Trailblazer only)

The engine requires a special engine oil meeting GM 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 GM standard. Look for and use only an oil that meets GM Standard GM4718M. For the proper viscosity, see "Engine Oil" in your owner manual

Engine Oil (Diesel Engine)

Engine oils with the letters CJ-4 are required for your vehicle. The CJ-4 designation can appear either alone, or in combination with other American Petroleum Institute (API) designations, such as API CJ-4/SL. These letters show API levels of quality. To determine the preferred viscosity for your vehicle's diesel engine, see "Engine Oil" in your owner manual.
