Engine
Mopar SAE 5W-20 engine oil approved to FCA
Material Standard MS-6395 such as Pennzoil,
Shell Helix Ultra or equivalent is recommended
for all operating temperatures. This engine oil
improves low temperature starting and vehicle
fuel economy.
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 the “Engine Compartment”
illustration in this section.
NOTE:
Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in
improper operation of the Fuel Saver Tech -
nology. Refer to “Fuel Saver Technology – If
Equipped” in “Starting And Operating” for
further information.
Lubricants which do not have both the engine
oil certification mark and the correct SAE
viscosity grade number should not be used.

engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in this
section 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.
Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number should not be used.
Shaker Hood — If Equipped
Shaker Hood Oil Filler
For vehicles equipped with a “Shaker Hood”,

Materials Added To Engine Oil
The manufacturer strongly recommends
against the addition 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.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used
engine oil and oil filters from your vehicle. Used
oil and oil filters, indiscriminately discarded, can
present a problem to the environment. Contact
an authorized dealer, service station or
governmental agency for advice on how and
where used oil and oil filters can be safely
discarded in your area.
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 disposable 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 ensure most efficient
service. Mopar engine oil filters are high quality
oil filters and are recommended.
ENGINE AIR CLEANER FILTER

Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.
T/A Air Filter Maintenance — If Equipped
Clean Engine Air Filter
The scheduled air filter cleaning interval is
30,000 miles (48,280 km), or if in a dusty
environment the engine air filter should be
checked periodically to ensure optimal air flow.
Cleaning your engine air filter with the
recommended Mopar Performance Air Filter
Service Kit is not required if you can still see any
part the wire screen on the entire air filter
regardless of how dirty it may appear. When any
part of the wire screen is no longer visible on the
air filter, that is an indication it is time to clean
the air filter.

1. Spray the air filter with the recommended
Mopar air filter cleaner and let sit for at
least 10 minutes to loosen dirt, before
rinsing.

NOTE:
Never use strong detergents, high pressure, or
gasoline on air filter. 2. Rinse the air filter with cool low-pressure
water applied from the inside (clean side)
out in order to flush the dirt out of the filter.
Continue to rinse the filter until all traces of
the cleaner have been removed.
NOTE:
It may be necessary to repeat steps 1 and 2 if
the air filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry
naturally. Do not apply oil until air filter is
completely dry.
NOTE:
Do not use forced air pressure as it may
damage the filtering capabilities of the filter’s
microfibers and also void its warranty.
4. Using the Mopar Performance Air Filter Service Kit, spray oil evenly along the crown
of each filter pleat holding the nozzle about
3 inches (76 mm) away from the air filter.
One spray per 2 square inches
(1,290 square mm) of air filter. With one
complete coat of oil, let it wick (saturate) for
about 20 minutes, and if required touch up
any light areas on either side of the filter.WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in
the case of engine backfire. Do not remove
the air induction system (air cleaner, hoses,
etc.) unless such removal is necessary for
repair or maintenance. Make sure that no
one is near the engine compartment before
starting the vehicle with the air induction
system (air cleaner, hoses, etc.) removed.
Failure to do so can result in serious personal
injury.
