I would do it after about 2000-3000 miles. You can use both the ford 5W30 FA-4 oil (WSS-M2C214-B1) , or a CK-4 5W40 (WSS-M2C171-F1). The FA-4 has a much lower HTHS viscosity which makes it easier to pump and thus yields better fuel economy. A CK-4 (i.e. rotella) is a heavy duty oil which ford recommends for "severe duty" service (towing, idling, stop and go, extreme temps, hilly terrain, and bio-diesel use). The CK-4 has a higher HTHS viscosity, so it will take more energy to pump, but it will yield a thicker film strength over components. Now the engine has been designed for FA-4 (new bearings, etc), so it's totally fine to use, however i'm more inclined to use the CK-4 oil as I plan on keeping the truck for a long time, and thus happy to sacrifice a 0.5 MPG fuel increase in the name of engine longevity. I may switch back at some point once we know there are no long term issues with FA-4. Ram had issues with 5W30 and switched to rotella 5W40 a couple years in, this FA-4 oil is even thinner at temp than the 5W30 ram started with. If you're in-between, Amsoil has a 5W30 CK-4 option that seems like a good middle ground. I'm in Canada and run Klondike 5W40.

I did my first two at 2500 and again at 5000. I will go 7000-10000 now.

You all do realize that the first engine oil fills on modern engines contain extra amounts of molybedieum to help break in the engine not to mention assembly paste and lubes used to help with engine break in as well. I would not change the oil till 5-6 thousand miles.

The paste is only there to protect the engine in the first few minutes of initial engine operation, after that all the "lube paste" is washed into the oil, which may give it higher molybdenum, however it's not really doing anything special at that point. There is no special oil that ford adds, just the usual recommended F150 diesel oil. Upon inspecting my oil filter on the first change, I found a number of small shavings of metal in there from manufacturing, so I was happy to drain that oil out sooner rather than later... molybdenum won't help you against that. But do what you're most comfortable with.

And you are really not doing anything by changing the oil sooner than the recommended schedule. Guess if it makes you feel better that all those shavings re removed from your oil filter but all engines have that as they break in. I usually use magnetic drain plugs which help as well some makers even put them into new vehicles. Most engine oils are formulated to run 10 thousand miles plus changing early does nothing but add to waste
