2012 Ram 5500 Chassis Cab oil viscosity

*No. 1 Ultra Low Sulfur Diesel Fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.
NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
•Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
•The engine requires the use of“Ultra Low Sulfur
Diesel Fuel”. Use of incorrect fuel could result in
engine and exhaust system damage. Refer to “Fuel
Requirements” in “Starting and Operating” for further
information.
Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Winter Front Usage
If a winter front or cold weather cover is to be used, a
percentage of the total grille opening area must be left
uncovered to provide sufficient air flow to the charge air
cooler and automatic transmission oil cooler. The per-
centage of opening must be increased with the increasing
ambient air temperature and/or engine load. If the
cooling fan can be heard cycling frequently, increase the
size of the opening in the winter front. A suitable cold
weather cover is available from your MOPAR dealer.
42 STARTING AND OPERATING

Engine Oil Viscosity (SAE Grade)
Use SAE 15W-40 MOPARor an equivalent engine oil
meeting Chrysler Material Standard MS-10902. 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), SAE 5W-40
synthetic engine oil that meets Chrysler Materials Stan-
dard MS-10902 and the API CJ-4 engine oil category is
required.
CAUTION!
Failure to use SAE 5W-40 synthetic engine oil in
ambient temperatures below 0°F (-18°C) could result
in severe engine damage. Engine oil not designated by the Chrysler or Cummins

Material Standards and API CJ-4 should not be used, as
engine and exhaust system durability may be compro-
mised. The engine oil filler cap also shows the recom-
mended engine oil viscosity for your engine. For infor-
mation on engine oil filler cap location, refer to “Engine
Compartment” in “Maintaining Your Vehicle” for further
information.
