LUBRICANT SPECIFICATIONS
Recommended lubricants
To help achieve proper engine and powertrain performance and
durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in
improved fuel economy.
Engine oils labeled Energy Conserving Oil are now available.
Along with other additional benefits, they contribute to fuel
economy by reducing the amount of fuel necessary to over-
come engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year's time, they can offer
significant cost and energy savings.
These lubricants and fluids are recommended for use in your
vehicle.

✽ ✽ NOTICE
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 (starting and oil flow). Lower vis-
cosity 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.
