Nick, I can kind of see why they don't see an issue. Your temps are not so terrible really. It looks to me like a maximum of 16° difference, and considering you were towing at the time I would say you might just be in the early stages.
I don't think the 15° is an absolute. But I don't really know.
I know that I didn't see those kind of temps until I towed up a hell of a hill here in CA. I think the logic in the new flash must take load and time into consideration, so even if you get the flash you might not exceed the parameters Ford has set. We talk about the 15° here all the time, but I have not yet seen any documention from Ford describing all the parameters required to set a CEL.
If you can manage it, you might want to hitch up your trailer and have the tech ride along with his monitor. OR, maybe you just need to speak directly with him and ask him what he considers the limits. Skip the service writer, he won't know jack. I don't know if you can do any of that, but consider it.
As I mentioned above, that DieselCare warranty is sounding better all the time.

Not to argue but you need to keep the SA involved since he writes the ticket that justifies the repairs. I have been very fortunate in having good SA's that listen and if they don't understand what I am saying then it's a trip to talk to the tech to get it right the 1st time. Knock on wood, hope I didn't just jinx myself.

I believe according to the TSB they check the EOT vs ECT with the truck empty (no trailer).
If you plan on keeping the truck the extended warranty might be something to look at. It is somewhere around $2,000 for 7 yr/200,000 miles, but you have to get it BEFORE your 5yr/100,000 mile warranty is up. My truck has been in the shop about 3 times under warranty and each time it cost Ford $2,000 or more.

Didn't ask for your history, asked where you got that number.

I think a lot of common engine knowledge does not translate directly to the 6.0.
I have no doubt that most any of todays oil can handle 250°. That's not really the issue. The issue here is whether the oil cooler is flowing coolant onward through another cooler, one which sees 1200° exhaust. The oil temps indicate that. That's what Ford says, in TSB 09-8-3. Apparently they only really became aware of this last year. So don't feel too slighted that your 40 years of engine rebuilding experience wasn't relative.
I'll leave the topic of "burning off other waste" for another time.

In any case, since the oil cools the undersides of the pistons, "spot" oil temps will easily get high enough to sufficiently burn off "wastes".
It just takes more time/distance than a couple of miles twice a day to get the engine heated up properly enough to do that.

"constant" short trips = bad;
Long drives and work your engine = good!
Good luck with the dealership. They may be receptive to your issue, but it truly is borderline.
There is a Ford customer service number in your owners manual if you do not get want you want with the dealership (or try another dealership).
