Yes, the plastic drain plug takes an o-ring. The BMW replacement oil filter included a plastic bag with replacement o-rings *and* a metal crush washer, but there was no need for the metal washer. I assume some other model takes the same oil filter and has a conventional metal oil plug (and pan) that takes the washer.
BTW, a low range torque wrench and 3/8" hex driver (socket) is good to have for reseating the oil drain plug, as the tightening spec (marked on the plug) is only 7 N-m (62 in-lb). You could do it by feel, but the tendency would probably be to over-torque it.
HTH,
