Visited my Indie MB/BMW shop the other day and he had a Mobil 1 0-30 ESP oil on the shelf. He said it was replacing the 5-40 ESP for my diesel MB. It had a MB 229.52 rating that supercedes all the others. It had a BMW long life rating and a diesel rating. Interestingly it came in Ltr. bottles not qts. He gets it from a MB dealer and they were the ones who told him because he ordered 5w-40esp. This is the same guy who reported sludging in gas engines using the ESP oils. Mobil sent 3 guys to visit him as he was reporting it on a mechanics forum that he moderates. They denied there was a problem but notified all MB dealers not to use ESP oils in gas engines. Mechanic thinks the acids in the alcohol react with something in the ESP oil to cause them to sludge within a normal oci. Some dealers were using the ESP oil in all there MB's to save confusion among the mechanics. The bottle states that it's good for gas engines.
