326 SERVICING AND MAINTENANCE
The manufacturer recommends the use of a full synthetic
SAE 0W-40 engine oil or equivalent meeting the require-
ments of FCA Material Standard MS-12633.
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.
Engine Oil Viscosity
Use Pennzoil Ultra Platinum 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 Compart-
ment" in this section for further information.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental additives.
Engine Oil Change Requirements — 6.2L
Supercharged Engine (If Equipped)
We recommend having your oil changed and vehicle
serviced by an authorized dealer. You should only perform
maintenance procedures and/or repairs for which you
have the knowledge and the right equipment.
Your 6.2L Supercharged engine (if equipped) has a unique
engine oil system. The system contains a drain in the
engine oil pan and the engine oil cooler. It is necessary for
the service technician to drain both the engine oil pan and
the engine oil cooler to properly perform the engine oil
change procedure. Failure to drain the engine oil cooler
will result in overfilling your vehicle's engine oil system.
NOTE: Do not overfill crankcase with engine oil, pressure
loss or oil foaming can result.
To access these oil drains, the vehicle needs to be safely
lifted and supported to remove the front underbody
shields (belly pan). Your service technician will refer to the
Service Manual for proper under body shield (belly pan)
removal and installation procedures.
An authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
