Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Synthetic engine oils which do not have both the engine
oil certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition 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 addi-
tives.
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 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 neces-
sary 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, pres-
sure loss or oil foaming can result.
