That’s a lot of words to not tell you anything.
10w-30 or 5w-40?
Tells quite a bit. This is where you'd need to rtfm ..... depending on your region and climate would determine your oil type per FCA recommendations. A truck in upper NY will not get the same weight as a south FL truck .
In ambient temperatures above 0°F (-18°C), we recommend using 10W-30
engine oil such as Mopar®, Shell Rotella and Shell Rimula that meets the
manufacturer 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 using 5W-40
synthetic engine oil such as Mopar®, Shell Rotella and Shell Rimula that
meets the manufacturer Material Standard MS-10902 and the API CK-4
engine oil category is required
