If I recall aright, the same size socket is also used for the drain plug bolt; somebody check me on this.

If you really get into doing your own changes, you could purchase a Topsider oil extractor. Do a search here for info. It let me get nearly all the oil out of the 420's engine (8 quarts!) by sucking the oil out through the dipstick tube. No electricity required, and once the oil is in the can, you seal it up and take it to recycling. No pans or splashing. Since the oil filter also lifts right out of the aforementioned housing, no oil messes there either.

Enjoy one of the greatest cars MB ever produced!
