For all trucks, regardless of model year, located in areas where the ambient temperatures routinely fall below 0°F (-18°C) during the winter, it is required to use 5W-40 synthetic engine oil that meets US Material Standard MS-10902, and API CJ-4. Oils that meet this requirement can be found through Mopar, as well as Shell in the Rotella and the Rimula families. Although this grade of oil is required in colder climate areas, it is also safe to use during the summer months, and in warmer climates as well.
However, for vehicles normally located in areas that routinely stay above 0°F (-18°C), there are two grades of engine oil recommended depending on the model year of the vehicle:
• 2018 model year, and older vehicles, it is recommended to use 15W-40 engine oil such as the Mopar, Shell Rotella and Shell Rimula branded oils that meets US Material Standard MS-10902 and the API CJ-4 engine oil.
• 2019 model year, and newer vehicles, it is recommended to 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.
CAUTION! 15W-40 grade oil CAN NOT be used in any 2019 model year or newer 6.7L equipped vehicles due to the new designed valve train of this engine. If this oil is used, it will cause deposits to form in the Hydraulic Valve Lash Adjusters leading to undesirable noise, and/or engine damage.
