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 impor-
tant 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 vis-
cosity (thickness) has an effect on fuel
economy and cold weather operating
(engine start and engine oil flowabili-
ty). 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. When
choosing an oil, consider the range of
temperature your vehicle will be oper-
ated 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-30 (ACEA A5). However, if the engine oil
is not available in your country, select the proper engine oil using
the engine oil viscosity chart.
* 2 : For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4 / ACEA A5).
However, if the engine oil is not available in your country, select the
proper engine oil using the engine oil viscosity chart.
