Recommended SAE viscosity number
Always 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 (engine start and engine oil
flowability). Lower viscosity engine oils can provide better fuel economy and cold weather performance, however, high-
er 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.
