Underbody — Corrosive
materials used for road-ice, snow
removal and dust control can
collect on the underbody. If these
materials are not removed,
accelerated corrosion (rust) can
occur on underbody parts such as
the fuel line, frame, floor pan and
exhaust system. At least once a
year, in the spring, flush these
materials from the underbody
with plain water.
Take care to thoroughly clean any
areas where mud and other debris
can collect. Sediment trapped in
closed areas of the frame should
be loosened before being flushed.
Proper Quality Oil
Engine oils are labeled on the
containers with various API
(American Petroleum Institute)
designations of quality.
Use Only SJ Quality Oil
Additional designations of quality
may also be present, but SJ must
be included.
The "SJ" designation may be
shown alone, or in combination
with other designations, such as
"SJ/CC," "SJ/CD," or "SJ, CC"
etc.
As long as the letters "SJ" appear
somewhere in the designation of
oil quality indicated on the
container, the oil is of suitable
quality.
Change Interval
The oil and filter change intervals
for your engine are based on the
use of the recommended oil
quality and viscosity, as well as
high-quality filters. Using oils
other than recommended, or
extending oil change intervals
longer than those recommended,
could reduce engine life.
Your engine was filled with a
high-quality engine oil when it
left the factory. You do not have
to change this oil before the
suggested change period.
If your normal driving does not
include one or more of the "severe
driving" conditions listed below,
change the oil every 7,500 miles
(12,000 kilometers) or 6 months,
whichever comes first.
