Selecting the right engine oil depends on both the proper oil specification and viscosity grade.
See Recommended Fluids and Lubricants.
Specification
Ask for and use engine oils that meet the dexos1 specification.
Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com.
Caution Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. |
Viscosity Grade
Use SAE 0W-20 viscosity grade engine oil for the LYX 1.5L turbo engine.
Use SAE 5W-30 viscosity grade engine oil for the LTG 2.0L turbo engine. 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, it is recommended to select an oil of the correct specification. See "Specification" earlier in this section.
