I don't want to have the last word on this issue but one clarification: new MB engines are designed for siphoning, the oil dipstick tube goes to the lowest part of the pan, if you do it properly, you don't get any oil from the plug.
You did not seem to claim that the sludge does not come out this way, this is a common argument. However if one does have that with modern oils and modern engines, then there are some real issues, other than just getting that out of the engine. (no more comments on this topic from me for this thread).
