Recommended SAE viscosity
number
CAUTION
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing 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.

* 1 : For better fuel economy, it is recommended to use the engine oil
of a viscosity grade 5W-30 (ACEA A5 or above). 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 or above). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil viscos-
ity chart.
