Dusty Conditions
Driving through dust-laden air increases the problems of
keeping abrasive materials out of the engine. Under these
conditions, special attention should be given to the
engine air cleaner, the crankcase inlet air cleaner and, the
crankcase ventilation system. Make sure that these units
are clean at all times. This will tend to reduce to a
minimum the amount of abrasive material that may enter
the engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that are API rated
as SL/CF and meet the requirements of DaimlerChrysler
Material Standard MS-10725. Use Mopar or an equivalent
oil meeting the specification MS-10725.
If you choose to operate this vehicle in a very aggres-
sive driving style, the manufacturer recommends the
use of a full synthetic engine oil, such as Mobil 1 SAE
0W-40.
