NOTE:
Hemi engines (6.4L) 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
distance. 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.

Approved Engine Oil
These symbols mean that the oil has been certified by the
API. The manufacturer only recommends API trademark
oils.

0W-30 and 5W-30 engine oils.
The API Donut trademark certifies 0W-40 and
5W-40 engine oil.
For diesel engines, oils with a high ash content
may produce damaging deposits on cylinder
head valves and/or after treatment system damage.
A maximum sulfated ash content of 1.00 mass % is
recommended for all oil used in the engine.
The same oil change interval is to be followed for synthetic
oil as for petroleum-based oil. Also, synthetic oil must
meet the same performance specifications as petroleum
oil.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
