5,000 mile interval on Rotella 15w-40 dino is my formula for both M-B diesels and any of them I'd ever own from about 1980 to 1995. Do whatever the owners manual says to do with dino 15w40 and you'll be fine. It's what was good enough in the year the book was written, it's still good enough if not better now.
