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 SAE 0W30 API SN PLUS / SP or ILSAC GF-6.
An engine oil displaying this API Certification Mark conforms to the
international Lubricant Specification Advisory Committee (ILSAC). It
is recommended to only use engine oils that uphold this API
Certification Mark.
