Some say 5000 for the first....some say 7500...some say wait until the dash tells you. I do 5000 for the first and 7000 every one after that. I don't haul heavy frequently though.
Bro in law is a ford diesel tech and he says they recommend 5k due to break in oil. But he also says 7500 to 10k is fine. If you tow over 10k 3-4 k miles he says to change every 5-6k. Just his 2 cents not sure if it's true.

There is still break in oil? Kinda thought that was a thing of the past. If so, other than lighter visc., wonder what it is. Break in is very interesting subject - a whole separate treatise.
The dealer likely won't provide 5w40 as a free first change. Do it yourself. It's not worth the trip to the dealer to get 10W30 for free. T6 is $21 a gallon at Walmart. The Motorcraft filter is $15 on Amazon. The oil change itself is one of the easiest you can do. What makes the second change even easier is to change out your drain plug for an EZDrain valve. Makes changing a no mess deal. Use a piece of tubing to drain the oil right into empty oil jugs and you won't even need an drain pan. For the filter, take a large screwdriver or hole punch and punch the filter before threading it off and it will drain right into a pan. Otherwise, the oil will run down the sides and make a mess. Here's a link to the EZ drain valve and the tube extension.
