Oil capacity by engine
| Engine | Oil Type (viscosity) | Capacity w/ Filter | Capacity w/o Filter | Notes |
|---|---|---|---|---|
| 1.2L — 1.2L Eng | SAE 5W-30 | 4.20 QTS. | — | DEXOS1 gen 2 full synthetic engine oil. In an area of extreme cold, where the temperature falls below -29Deg.C (-20Deg.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. |
