Fema, you know what you're getting into from the discussion... The whole problem is that MB put the drain plug on the side of the oil pan. The best way to avoid the issue is to suck the oil out (with TopSider or another product). Or, make the home-made funnel like I did. It's not perfect but it works pretty good and makes the oil change cost less than $50. (if you buy the filter kit online (not the dealer). Good luck.
