Recommended SAE viscosity
number 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 perform-
ance, however, higher viscosity engine
oils are required for satisfactory lubrica-
tion in hot weather. Using oils of any vis-
cosity 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, 5W-30 (API SL, SM / ILSAC GF-3). However, if the engine oil is not available in your coun-
try, select the proper engine oil using the engine oil viscosity chart.

CAUTION
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or drain-
ing 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.
