302 SERVICING AND MAINTENANCE
Engine Oil Selection — Non-SRT (If
Equipped)
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils
that are API Certified and meet the
requirements of FCA Material Standard
MS-6395.
NOTE:
Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approxi-
mately 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 distance. Upon restarting, you may experi-
ence 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.
Engine Oil Selection — SRT (If Equipped)
For best performance and maximum protection
under all types of operating conditions, the

Institute (API) categories of SN.
The manufacturer recommends the use of
Pennzoil Ultra 0W-40 engine or equivalent
Mopar oil meeting the FCA Material Standard
MS-12633 for use in all operating
temperatures.
The engine oil filler cap also shows the
recommended engine oil viscosity for your
engine. For information on engine oil filler cap
location, refer to "Engine Compartment" in this
