Oil capacity by engine
| Engine | Oil Type (viscosity) | Capacity w/ Filter | Capacity w/o Filter | Notes |
|---|---|---|---|---|
| GS, Automatic Trans — 2.0L Eng | API - SAE 5W-30 | 6.30 QTS. | — | Use only engine oil licensed to the dexos1 specification or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended. SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50. If in an area of extreme cold, where the temperature falls below -20Deg.F (-29Deg.C), 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. |
