Recommended Lubricants and Capacities

~2min read

To achieve proper engine and transmission performance and durability, use only lubricants of the proper quality. Proper lubricants also contribute to engine efficiency, which improves fuel economy.

*1: Refer to the recommended SAE viscosity values on the following page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they help save fuel by reducing the amount of fuel needed to overcome engine friction. Often these improvements are difficult to measure in everyday driving, but over time they can offer significant cost and energy savings.
*3: If ACEA C2 engine oil is not available in your country, you may use ILSAC GF-3 (or higher) or ACEA A3 (or higher).

CAUTION

Always clean the area around the oil filler cap, drain plug or dipstick before checking or draining lubricant. This is especially important in dusty or sandy areas and when driving on unpaved roads. Cleaning the filler cap and dipstick area prevents dirt and sand from entering the engine and other mechanisms, which could be damaged.

Engine oil viscosity (thickness) affects fuel economy and operation in cold weather (engine starting and engine oil flow). Lower viscosity engine oils may provide better fuel economy and cold-weather performance; however, higher viscosity engine oils are necessary for adequate lubrication in hot weather.

Using oils of any viscosity other than the recommended one may cause engine damage.

When selecting oil, consider the temperature range in which your vehicle will be operated until the next oil change. Refer to the chart to select the recommended oil viscosity.

*1: For best fuel economy, it is recommended to use engine oil of SAE viscosity grade 0W-20 (API SN (or higher) or ACEA C2). However, if this engine oil is not available in your country, select a suitable engine oil based on the viscosity chart.
