Engine CoolantWe recommend you use Mopar Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT (Organic Additive Technology).
Engine Oil In ambient temperatures above 0°F (-18°C), we recommend you use 10W-30 engine oil such
as Mopar, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902 and the
API CK-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-40
synthetic engine
oil such as Mopar, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902
and the API CK-4 engine oil category is required.
Engine Oil Filter We recommend you use a Mopar Engine Oil Filter. If a Mopar Engine Oil Filter is unavailable
only use filters that meet or exceed SAE/USCAR-36 Filter Performance Requirements.
Fuel Filters We recommend you use Mopar Fuel Filter. Must meet 3 micron rating (engine mounted filter).
Must meet 5 micron rating (chassis mounted filter).
Using a fuel filter that does not meet the
manufacturer’s filtration and water separating requirements can severely impact fuel system
life and reliability.
Crankcase Ventilation Filter We recommend you use Mopar CCV Filter.
