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 operation (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory 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 tempera-
ture your vehicle will be operated in
before the next oil change. Proceed
to select the recommended oil vis-
cosity 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). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil vis-
cosity chart.
