FLUIDS, LUBRICANTS AND GENUINE PARTS
Engine
Component Fluid, Lubricant, or Genuine Part
Engine Coolant We recommend you use MOPAR Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT
(Organic Additive Technology).
Engine Oil In ambient temperatures above 0°F (-18°C), we recommend you use 15W-40 engine oil such
as MOPAR, Shell Rotella and Shell Rimula that meets FCA US Material Standard MS-10902
and the API CJ-4 engine oil category is required. Products meeting Cummins CES 20081
may also be used. The identification of these engine oils is typically located on the back of
the oil container.
In ambient temperatures below 0°F (-18°C), we recommend you use 5W-40synthetic
engine oil such as MOPAR, Shell Rotella and Shell Rimula that meets FCA US Material
Standard MS-10902 and the API CJ-4 engine oil category is required.
Engine Oil Filter We recommend you use MOPAR Engine Oil Filters.
Fuel Filters We recommend you use MOPAR Fuel Filter. Must meet 3 micron rating.Using a fuel filter
that does not meet the manufacturers filtration and water separating requirements can
severely impact fuel system life and reliability.

Component Fluid, Lubricant, or Genuine Part
Crankcase Ventila-
tion FilterWe recommend you use MOPAR CCV Filter.
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law re-
quires that you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15
ppm Sulfur maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500
ppm Sulfur maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade
S15 will provide good performance.
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to operate
at colder-than-normal conditions for prolonged periods, use climatized No. 2 diesel fuel
or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better pro-
tection from fuel gelling or wax-plugging of the fuel filters.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting
ASTM specification D-975.Pickup models, and Chassis Cab models configured with op-
tional B20 capability, are additionally compatible with 20% biodiesel meeting ASTM specifi-
cation D-7467.

MAINTENANCE SCHEDULE — DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accuracy
of the oil level reading. Add oil only when the level is at
or below the ADD or MIN mark.Once A Month
•Inspect the batteries, and clean and tighten the termi-
nals as required.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, and automatic transmission (if
equipped), and add as needed.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect engine air filter.
•Check the coolant level, hoses, and clamps.
•Lubricate outer tie rod ends.
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.
334 MAINTENANCE SCHEDULE
Page 338 of 360

NOTE:
•Under no circumstances should oil change intervals
exceed 15,000 miles (24,000 km) or six months or 500
Hours, whichever comes first.
•Replace the engine oil and oil filter every 12,500 miles
(20 000 km) when running B20 fuel (Chassis Cab
Only).
If Chassis Cab models are operated with greater than 5%
levels of Biodiesel, the oil change interval must not
exceed 12,500 miles (20 000 km) under any circumstances.
See the Fuel Requirements section for more information
regarding operation of Chassis Cab models configured
for use with Biodiesel blend (B6-B20) fuel meeting ASTM
specification D-7467.Perform Service Indicator — Cummins® Diesel
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC) will
display “Perform Service”. When the “Perform Service”
message is displayed on the EVIC it is necessary to have
the emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure for clearing
and resetting the “Perform Service” indicator message is
located in the appropriate Service Information.
