On your car, any of those would be fine. I believe a c220 would fall under the old 229.1 spec....if not something prior. What I would be more concerned about are leaks. A synthetic at that thin of a weight will probably begin leaking if you're on the original head gasket. It just flows better. How many miles? My suggestion would be Mobil 1 15w50 extended life.
