Not questioning you, as I'm running M1 TDT 5w40 in my Ram EcoDiesel, but where are you getting that it's "robust"?
All I ever hear is that it's the weaker little brother of Delvac 1 because it doesn't have many manufacturer approvals and that if you want a stout and robust oil you should choose Delvac 1.
I chose M1 TDT 5w40 because I got it for $10/g and it meets all of the requirements my EcoDiesel calls for.
Last I checked, M1 TDT does NOT have MS-10902/Cummins CES 20081, so it is not an oil that meets all of the specs unless that changed.
Delvac 1 ESP 5W40 has Cummins CES 20081 along with just about every other builder approval.
You're right, M1 TDT doesn't meet CES 20081 but it does meet one of the other options of meeting E7/E9 and it also meets CK-4. So I shouldn't have said that it meets all of the options.
And since CK-4 supersedes CJ-4 and is backwards compatible my logic is:
MS-10902 = CES 20081
CES 20081 = CJ-4
CJ-4 superseded by CK-4
So it also meets one of the other options.
I'd be curious to see a UOA of someone who has ran A3/B4.
It's kind of amazing that FCA is pretty much saying that you can run any oil as long as it is mid SAPS.
(Garak is WAY better at explaining this than I am)
