CAUTION!
•Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately
have potential malfunctions examined by an autho-
rized dealer or qualified repair center.
•
Your vehicle has been built with improved fluids that
protect the performance and durability of your vehicle
and also allow extended maintenance intervals. Do not
use chemical flushes in these components as the chemi-
cals can damage your engine, transmission, or air con-
ditioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed because
of component malfunction, use only the specified fluid
for the flushing procedure.
Engine Oil
Checking Oil Level — 3.6L Engine
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as once a month. The best time to
check the engine oil level is about five minutes after a fully
warmed engine is shut off. Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level between the MIN and MAX markings on the
dipstick. Adding 1.0 quart (1.0 liter) of oil when the reading
is at the MIN mark will result in a MAX reading on these
engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Checking Oil Level — 5.7L and 6.4L Engine
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level in the “SAFE” range. Adding 1.0 quart (1.0 liter) of
oil when the reading is at the bottom of the “SAFE” range
7
MAINTAINING YOUR VEHICLE 447
Page 450 of 530

will result in an oil level at the top of the “SAFE” range on
these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Change Engine Oil — 3.6L and 5.7L Engine
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
Change Engine Oil — 6.4L Engine
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to “Maintenance Schedule” for further information. NOTE:
Under no circumstances should oil change inter-
vals exceed 6,000 miles (10,000 km) or six months, which-
ever occurs first.
Engine Oil Selection — 3.6L and 5.7L Engine
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends engine oils that are API Certified and meet the
requirements of FCA Material Standard MS-6395.
Engine Oil Selection — 6.4L Engine
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends full synthetic engine oils that meet the American
Petroleum Institute (API) categories of SN.
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.

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has been
certified by the American Petroleum In-
stitute (API). The manufacturer only rec-
ommends API Certified engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30, 5W-30 and
10W-30 engine oils.
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 (SAE Grade) — 3.6L Engine
Mopar SAE 5W-20 engine oil approved to FCA Material
Standard MS-6395 such as Pennzoil, Shell Helix or equiva-
lent 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 Compart-
ment” illustration in this section.
NOTE:
Mopar SAE 5W-30 engine oil approved to FCA
Material Standard MS-6395 such as Pennzoil, Shell Helix or
equivalent may be used when SAE 5W-20 engine oil
meeting MS-6395 is not available.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity (SAE Grade) — 5.7L Engine
Mopar SAE 5W-20 engine oil approved to FCA Material
Standard MS-6395 such as Pennzoil, Shell Helix or equiva-
lent 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 Compart-
ment” 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 opera-
tion of the Fuel Saver Technology. Refer to “Fuel Saver
Technology – If Equipped” in “Starting And Operating” for
further information.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity — 6.4L Engine
Use Pennzoil Ultra 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 “Maintaining Your Vehicle” for further informa-
tion.
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 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.
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 your authorized dealer, service sta-
tion 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 oil filter.
Use a filter of this type for replacement. The quality of
replacement filters varies considerably. Only high quality
