Vehicle Information
Recommended SAE Viscosity
Number
CAUTION
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 *
1
Requires <API SN PLUS (or above) Full synthetic> grade engine oil. If a lower grade
*1 :
engine oil (mineral oil including Semi-synthetic) is used, then the engine oil and engine
oil filter must be replaced as indicated for severe maintenance condition.
An engine oil displaying this American Petroleum Institute(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.

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.
