An engine oil displaying this American Petroleum Institute (API) Certification
Mark conforms to the International Lubricant Specification Advisory Com-
mittee (ILSAC). It is recommended to only use engine oils that uphold this
API Certification Mark.
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 viscosity (thickness) has an effect on fuel economy and cold weather oper-
ating (engine start and engine oil flow ability). 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 oper-
ated in before the next oil change. Proceed to select the recommended oil viscosity
from the chart.
