Dodge Challenger SRT 392 2015 Operating Information Manual page 265

Engine Oil Viscosity
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends full synthetic
engine oils that meet the American Petroleum
Institute (API) categories of SN.
The manufacturer recommends the use of Pen-
nzoil Ultra™ 0W-40 engine or equivalent
MOPAR® oil meeting the Chrysler Material
Standard MS-12633 for use in all operating
temperatures.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your engine. For
information on engine oil filler cap location, refer
to "Engine Compartment" in "Maintaining Your
Vehicle" for further information.
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed.
Materials Added To Engine Oil
The manufacturer strongly
against the addition of any additives (other than
leak detection dyes) to the engine oil. Engine oil
262
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 your authorized dealer. You
should only perform maintenance procedures
and or repairs for which you have the knowl-
edge 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
recommends
be safely lifted and supported to remove the
front underbody shields (belly pan). Your ser-
vice technician will refer to the Service Manual
for proper under body shield (belly pan) removal
and installation procedures.
Your authorized dealer has the qualified service
personnel, special tools, and equipment to per-
form all service operations in an expert manner.
Service Manuals are available which include
detailed service information for your vehicle.
Refer to these Service Manuals before attempt-
ing any procedure yourself.
WARNING!
You can be badly injured working on or
around a motor vehicle. Do only that service
work for which you have the knowledge and
the right equipment. If you have any doubt
about your ability to perform a service job,
take your vehicle to a competent mechanic.
Shaker Hood Oil Filler — If Equipped
For vehicles equipped with a "Shaker Hood" the
