Vehicle Information, Consumer Information and Reporting Safety Defects  
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 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.

Requires API SN PLUS(or Above) grade engine oil. If a lower grade engine oil is used, then  
the engine oil and engine oil filter must be replaced at every 5,000 miles.  
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.
