426 MAINTAINING YOUR VEHICLE
CAUTION!
Do not overfill the engine. Overfilling the engine
will cause oil aeration, which can lead to loss of oil
pressure and an increase in oil temperature. This
could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the Maintenance Schedule in Section 8 for
information on this system.
NOTE: Under no circumstances should oil change
intervals exceed 6,000 mi (10 000 km) or six months,
whichever occurs first.

types of operating conditions, the manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Chrysler Material Standard MS-6395.
