✽ ✽ 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 pre-
vent 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 viscosity engine oils can
provide better fuel economy and cold
weather performance, however, high-
er 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.
