I have a 2007 Nitro 2.8, Diesel and have now been able after some time to locate the oil filter.
It can be found from the top of the engine just in front of the oil dip stick, look for a black dome with a hexagonal lump.
Unscrew and you will find it inside.

It depends on the oil filter.
4.5 quarts.
4.5 quarts
probably 4 quarts then 1 more with the filter change
5 qts with filter
5 qts with filter change.
should be 4.7 L of oil if you change the filter
The same way you change the oil on any vehicle. Drain the oil, change the filter, and add the correct amount of oil and the correct weight.
Key on engine off, press the gas pedal to the floor three times.
