Lubricant specifications
These lubricants and fluids are recommended for use in your vehicle.

*1 Refer to the recommended SAE viscosity numbers.
*2 If the API service SM engine oil is not available in your country, you are able to
use API service SL.
Recommended SAE viscosity number
NOTICEAlways be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining any lubricant.
This is especially important in dusty or sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick areas will prevent dirt and grit from entering the engine and other mechanisms that could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather operating (starting and oil flow). Lower viscosity engine oils can provide better fuel economy and cold weather performance, however, higher viscosity engine oils are required for satisfactory lubrication in hot weather. Using oils of any viscosity other than those recommended could result in engine damage.When choosing an oil, consider the range of temperature your vehicle will be operated in before the next oil change. Proceed to select the recommended oil viscosity from the chart.

*1. For better fuel economy, it is recommended to use the engine oil of a viscosity
grade SAE 5W-20 (API SM / ILSAC GF-4).
