Something else that I'm thinking about is that, at least on a 124 and 126, you still have lots of oil in the oil cooler that you cannot get out unless you disconnect the lines, so the oil will never be really clean. In my case, I just changed my oil last Saturday and today is black as ink. I don't know the percentages though. When i get a garage to work in I would probably consider disconnecting those lines to get out all the dirty oil...
