Let's be careful with the terminology we're using.
Mobil Devlac 1 in 5w-40 is their HDEO PAO based product, marketed for the large diesel fleet markets. You can find it out there, but it's pretty much at heavy/OTR truck places most of the time, typically in gallons or pails.
Mobil Turbo Diesel Truck (TDT) in 5w-40, is (from what I gather) basically the same as Delvac 1, marketed for small user consumption (auto parts stores and Wally World). Most often seen in individual quarts. (It may not be the exact product as Delvac 1, but it's darn close!).
Mobil Truck and Suv is NOT the same at TDT. It's likely a fortified gasser product, and not HDEO. And I've not seen it in 5w-40, but that doesn't mean it's not out there. Most often seen in 5w-30 or 10w-30. Not a viscosity preferred in most motorcycles.
I would stick with the HDEOs for motorcycle/ATV applications, and trend away from gasser-based products.
