Chisel and Hammer. The drain plug is sacrificial. A new one is cheap. I had this happen to me on my 1986 190E 2.3-16. First oil change, could not get the drain plug out. Took it to a shop near by and had them do it, and they used a hammer and chisel. The next time I tried to take it out, it was stuck again. I bought a fancy socket from Snap-On that has the corners drilled out so you exert force on the flats only. Still would not budge, and started getting deformed. Got a new plug, then used a hammer and chisel and it came right out. The drain plug on these cars has about two inches of thread and is steel going into aluminum. I bought two more plugs, and when the third one got stuck, I invested in a Topsider. Never had the problem again, although I have never tried to take the drain plug out. It was really wierd, as I made sure I was not over tightening the thing, yet it would get stuck every time. The last drain plug is still in the center console tray, just in case. Hope this helps, Jim
