Mobil 1 5W-40 ESP Formula M

If "ESP Formula M" isn't on the bottle, it's the wrong oil.
I've asked about this from the dealership I go to and he says that the Mobil1 5W-40 that you see in any auto parts store as long as it says synthetic oil is fine. He says that the oil they use only says Mobil1 5W-40 and come in a big drum. The one I saw from Advance auto parts says Mobil 1 5W-40 Synthetic oil for Diesel engine. I guess this is the same although it does'nt say ESP Formula M. Can anyone confirm this.
