I thank you for the input. I think you are right about the EGR sending all the exhaust back through the oil. I am surprised to only get one comment, i would have thought RAM would have chimed in.
I have a 2015 EcoDiesel that always has dirty oil. Always changed as book. All TSBs & recalls taken care off. The Cummins that i had for 12years was always clean. I change the oil and 100 miles later it is dirty are they all like this ? The oil filter is factory & the oil is Rotella T6 5/40
