Best Oil Choice/s

[EcoDieselJolene]

New owner of a '17 EcoDiesel, and I'm coming due for an oil change within a week or so.
I'm not sure about the rest of the country, but 5w40 diesel oil isn't the easiest thing to find (especially the T6). I can find some brands, like the Mobil Delvac ESP 5w40. I've always preferred Mobil 1 in my other vehicles.
Does anyone have any good, objective information to share about the Mobil Delvac, or any other good alternatives to the T6?

Thanks for the suggestion.
Any particular reason for this one over the Delvac?
Also, this isn't one I can seem to find.

That's what I settled on. Just bought some more at Napa for $21.99/gallon.
