Anyway, if you want to use synthetic, then let the OCI run until the car tells you to change oil, otherwise dino will do the same job as synthetic at 5-6k OCIs
EDIT:
I stand correced, it is a DI engine. In this case I probably would not use dino for more than 4k, maybe even 3k max.
As you found out it does.
And I'd NEVER run an extended OCI (esp a 10k) with that engine EVER.
Changing the oil is a GOOD thing with DI motors. Any 5w-20 oil rated SM/SN would be your BEST bet with it getting changed on whatever severe service OCI is listed in the manual.
Don't give Ford any reasons for warranty concerns *IF* needed.

PS: Need a reason why DI motors are "special"?
