5W40 or 15W40 in 6.7 CTD?
So the owner's manual in my 2015 Ram says to use 15W40 oil in the 6.7 Cummins diesel, unless the temp is going to routinely be below 0*, in which case you should use 5W40. Here on Long Island, the ...

Sounds like a perfectly legtimate explanation to me. If this is the case, gotta wonder what specific issue in that 6 mo. to 12 mo. MTBF/OCI data pushed their warranty costs high enough to warrant a 6 mo. OCI? Hhhmmm . . .
$$$$ is part of the explanation. They are hoping you bring your shiny new Ram back to the dealer for that 6 month service. They are going to charge you $150+ for an oil change that costs less than $85 for oil and filter. Oh, and there's always the up-sell of other services that a lot of people buy once they're in the door.

This is true as well! And there are many gullible owners than do not know any better that will follow suit without question.
This kind reminds me of a friend who traded in his VW Tiguan for an Audi Q3 which is essentially the same thing with the same engine, but the Tiguan is slightly detuned. Even though they were basically the same, the Audi had a laundry list of extra maintenance items that the dealer would throw at him every time he came in for an oil change that they did not with his Tiguan. I guess they assume that people who buy such vehicles are more gullible and/or are less concerned about such things.
The local Infiniti dealer tried to do the same with my wife not too long ago. She went in for a 50k mile service and tried to tell her that she needed to replace all of the coolant hoses and a list of other things totaling over $750. I told her to hand her phone over to the service writer after she told me this, and I told him that if this SUV needs all of this at at 50k then Nissan/Infiniti must used cheap parts and the vehicles is a pile of junk. No vehicle I have ever owned has needed this kind of stuff at 50k, and that I will be trading it in if that is the case. It was after this that he changed his tune and said it was "recommend" not needed like he was telling my wife to scare her into paying.
Although at first he was trying to explain why it was needed, but I then told him my background and what I do for a living and he stopped after figuring out that I probably know more about engines and vehicle than he does.
