About 1,800 miles on the M1 0w30 ESP and my Benz seems to love it. Warms up quickly even in sub-freezing temps, quieting the engine's normal diesel clacketies nicely in seconds, and my FE seems to have slightly improved even in the cold using winterized fuel.
I may stick with this oil from now on year-round. I'm only at 139K miles so we'll see how the next 40-50K go.
