oil change
I am usually on the obs 7.3l but have a question on my sons 2019 6.7l. been having bartow ford do oil change at 7000. Today he is doing his oil change at my place and the oil is really black. Is this normal at 7000 mi. ? My 7.3 l would not be even close to that black and it has 350k on it. If not normal what would cause this. ? TIA

You are seeing the joys of a emissions compliant diesel, EGR loads up the soot in the oil. Totally normal, even my 04.5 CR Cummins with the 3rd injection event would turn the oil black immediately upon first start up. CJ and CK-4 oils are actually designed to hold the sub-micron soot in suspension so it looks a lot worse than it is. My old 2002 would have gas engine looking oil for 4500-5000 miles before it would start to darken.

Yea, I am used to my 7.3l so when I saw that black stuff at 7k I sorta went like what the heck. Thus I came here. Thanks again.
