That's a long way in a fully smog burdened modern diesel without bypass filtration.

The manual says to change it when the oil life monitor says so, it also includes some examples of when that might be. That 7500-10k might be what they say you can expect from normal use, I personally think that is too long. They also say not to exceed 1 year or 10k miles.

If they included language saying that there is in fact break in oil that should be left in for x amount of time that would be one thing, but being that it's uncertain I chose to do an early first change.

Hmmmm…. We’ll then that’s the key for me. Is there or isn’t there a special oil additive from Ford at delivery???

No. And this notion of the factory using a break in oil is myth. And no additives of any kind. There was a time, decades ago, where detergent oils were not recommended for engine run in and the break in period. But there was nothing special about a non-detergent oil. You can still buy it today. It's mostly used for lawn mowers and non-combustion applications, like air compressors. It's principle advantage is that most everything in the bottle is oil, and not the additives used to make it multi-grade, detergent and so on. And engine break in occurs in very short order, like by the time you get the truck home from the lot. The days of taking 5,000 miles to seat chrome-faced rings were pretty much over in the '60s. You do get some incidental metals shed into the oil that some refer to as break in metals, but those are very modest amounts. The filter will generally catch most of that. It's very inconsequential.

its not just a jab at ford. other vehicle manufacterers are no better about the maintenance intervals. do you think the brilliant engineers care one bit if that vehicle is still in good running order at 200k or 300k. hell no they dont care. owners have to take matters into their own hands
First, they are not the same people. There are numerous design teams that work independently on the particular systems they are responsible for.
Second, even I don't care if the truck is in good running order at 200k or 300k. I think the majority of first owners will never get past 100k. Furthermore, I don't think doing the initial oil change at 1k or 2k will make a meaningful difference in the engine going for 200k miles. There are too many other factors involved.

Of course, this is just my opinion.

I do first oil changes early in trucks and equipment but then stick to manufacturer recommendations. Like my truck I wait til about 10% remaining and fuel filters every 30k.

If changing the oil makes you feel better about any of these items, then go for it.

They are also the same people that designed and built the 6.7 PS so there is that

DIY oil changes are still fairly inexpensive so the bottom line is do whatever makes you feel better with regards to you and your truck. It's win -win all the way around.
