They could save even more than that, by skipping McDonalds for the 500k duration.

I forgot to mention, Mercedes used Mobil 1 for high mileage testing and engine disassembly.
But 10k is the oci set by Ford.
Does that meet the performance level set by Ford, if any?
Whoa whoa whoa! You leave drugs and booze out of this!
Generally speaking synthetic oil will produce less varnish. I don't think there is any surprise.

That's a broad statement that needs to be qualified to be valid.
In some circumstances, 10k miles with conventional is super easy and perfectly acceptable. I've done 10k and more on ST and RK conventional oils and the UOAs were fine. In fact, those low dollar oils did every bit as well as popular syns. But, that's because these were done in 4.6L and 3.5L n/a Fords. These engines are very easy on oil; they run clean and don't stress the oil at all. My UOAs are posted here on the site as proof.
In other circumstances, 10k miles would be too much. High stress engines, especially ones that have turbos that run very hot, along with a fairly small sump capacity, would likely degrade the oil quick enough that longer OCIs can result in problems.
It's very important to make sure we state the full conditions of all the inputs to the equation. Just stating 10k miles is too much for lube "X" is an unbounded statement fraught with potential for misleading errors.
Interesting. The cleanliness of both of these engines are a far cry from the sludge monsters that pop up on my social media account’s claiming 10k changes. FordBossMe is one that has everyone convinced your rings will be coked closed if you don’t change at 5k or less regardless of oil type used.
I stopped watching that idiot a long time ago..
Yes, GDI only.
Sure, it is the OCI set by Ford's marketing department and will serve Ford well as they don't care about engine wear past the warranty period. I bet if you talked to the engineers privately (key word being privately) they would recommend a shorter OCI.
I mean, I believe in 5K intervals and that is completely separate from what that nitwit says.

In cases like this I will often refer to our own member tig1 who has owned many Fords and has done 10k intervals with M1 for about 40 years now and routinely gets over 300k+ out of his cars with no engine issues.
Marketing has nothing to do with OCI. OCI are set by engineering and would be validated by engineering. Sure, shorter might be better, but the OCI listed in the manual would have been set and validated by engineering long before marketing would have gotten a hold of anything.
OCI isn't set by the engineers at automakers. It is set by the marketing department.
Here a prior Toyota automotive production engineer explains. MIT/BC affiliated engineers know more about this than you or I do.

Sure, and my grandpa smoked tobacco until he was about 98. That doesn't mean it was good for him. Anecdotal info.
