Recommended SAE Viscosity Number
CAUTION
Always be sure to clean the area around any filler cap, 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, 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.
