The oil turns black from all the soot introduced into the oil from the 3rd injection event which is a in cylinder egr. Happens to all CTD with the 3 injection events. I don't recall offhand which years all had this but I know for a fact 2005 is one because that's what I have. Oil turns black immediately.
All Diesels turn the oil black quickly not just Ram/Cummins....
