ENGINE OIL
Engine Oil Selection Non-SRT
Use only the manufacturer's recommended fluid
page 305.
NOTE:
Hemi engines at times can tick right after startup and
then quiet down after approximately 30 seconds. This is
normal and will not harm the engine. This characteristic
can be caused by short drive cycles. For example, if the
vehicle is started then shut off after driving a short dis-
tance. Upon restarting, you may experience a ticking
sound. Other causes could be if the vehicle is unused
for an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine continues
to tick or if the Malfunction Indicator Light (MIL) comes
on, see the nearest authorized dealer.
