Change Engine Oil
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
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
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends full synthetic engine oils that meet the require-
ments of FCA Material Standard MS-12633.
The manufacturer recommends the use of a full synthetic
0W-40 or equivalent engine oil.
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) — 8.4L
Use MOPAR SAE 0W-40 engine oil approved to FCA
Material Standard MS-12633 such as Pennzoil Ultra
equivalent is recommended for 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 this section.
Lubricants which do not have both the engine oil certifi-
cation 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.
268 MAINTAINING YOUR VEHICLE
CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
VEHICLE STORAGE
We recommend that you follow these guidelines for storing
your vehicle for extended periods.
• Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than two months, add an anti-oxidant fuel stabilizer to
the fuel tank.
• Change the oil to remove any corrosive combustion
related acids in the crankcase. •
Check that the radiator coolant level of protection is to at
least -20°F (-29°C).
• Make sure that all tires are inflated to the optimum
pressure.
• Wash and wax the vehicle to protect the finish.
• Store the vehicle in a dry, well-ventilated location.
• Move the wiper blades away from the windshield.
• Block the wheels. Do not apply the parking brake.
• Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
• For long-term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
• If the vehicle will be subjected to freezing temperatures,
either remove the battery and store it in a dry, well
ventilated area or connect a trickle charger (1.5 Amp)
with automatic shutdown / overcharge protection to the
battery. However, do not leave the trickle charger
hooked up to the battery without being plugged in to a
110 Volt AC outlet, as this will result in further drain on
