I have been using synthetic S rated oil in the E320, and the C rated oil in the old Diesels. I have not tried C rated oil in the newer gas engines (mine and a friend's M112), but desire to go with one oil for everything.

Bottom line: I am only looking for actual real world statistics and/or experience that would sway me from running 15-40 C rated oil in my M112.
