Recommended Lubricants and Capacities
To ensure proper engine and transmission performance and durability, use only lubricants of the proper quality.
Proper lubricants also help improve engine efficiency, which results in improved fuel economy.

*1: See the recommended SAE viscosity grades on the following page.
*2: Engine oils labeled Energy Conserving Oil are now available. In addition to other benefits, they help improve fuel economy by reducing the amount of fuel needed to overcome engine friction. These improvements are often difficult to measure in everyday driving, but over a year they can provide significant cost and energy savings.
*3: If API Service SM engine oil is not available in your country, you may use API Service SL.
