Here is some information copied and pasted from the online 2013 Charger SRT8 Maintenance Manuel. :bigthumb:

"Use of genuine MOPAR
parts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR
parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty."
"Engine Oil Selection
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 SM or
SM/CF.
The manufacturer recommends the use of a full synthetic
SAE 0W-40 engine oil or equivalent."
"Engine Oil Viscosity
SAE 0W-40 Full Synthetic engine oil is preferred for use
in all operating temperatures."
"Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. MOPAR
engine oil filters are a high quality oil
filter and are recommended"
"NOTE: Under no circumstances should oil change in-
tervals exceed 6,000 miles (10 000 km) or six months,
whichever occurs first."

Looks like to keep my SRT8 under full warranty I need to keep using genuine Mopar oil filters and any high quality full synthetic SAE 0W-40 full synthetic. :beerchug:
