Follow the link below to buy the right oil type for your engine.
| Oil Type | Oil Capacity | Filter | |

If you do not choose to buy the recommended Toyota oil, you should try to always buy oil that has the API-certified logo on it.
This will ensure that the oil you are putting in your car conforms to the engine, emission system, and fuel economy standards set by the International Lubricants Specification Advisory Council.
And lastly, DO NOT USE SUPPLEMENTAL ENGINE OIL ADDITIVES!
