The new Mobil 1 ESP Formula M 5W-40 is a new oil and not yet available anywhere as far as I can tell. It's a "longlife low SAPS oil", low in sulfated ash and phosphorus and also with low vapor pressure so it wont pollute the exhaust particle filter. It extends the oil service interval to 20,000 km / 12,500 mi. It complies with the new MB oil recommendation 229.51 which should be printed on the can so one can differentiate it. It's probably based on Mobil 1 0W-40 or Mobil 1 0W-40 Turbodiesel, both of which have 229.3 and 229.5 approvals.

Mobil Delvac 1 5W-40 228.5 should be fine, although formulated a bit different for commercial diesel trucks. There's now also a Delvac low SAPS oil for those commercial trucks with Bluetec. It's the new Mobil Delvac XHP LE Extra 10W-40 228.51.

My feeling is that if you change your oil at intervals of around 3-5000, you don't need the special properties of the newer long life oils. Only if you want to run the interval change to the limit, do you need these oils. Just a gut feeling. No proof. Running Mobil 5-40 Delvac. Oil and MB filter change at 5000 mile intervals. Do it myself, using a Liquidynamics Oil Evacuator.
