I have to agree with some of you because of some generalizations gleaned from seeing hundreds of FF UOAs over the years.
They have no value if you're interested in establishing wear metal ranges for analysis. We all know the metals will be way high, and they should come down. If that is the intent, it's silly, but that is my opinion, and yours may vary. On this one, I see nothing that is alarming from FF point of view.
If the intent is to check things that are independent of break-in, that are expected to be consistent throughout the use cycles, then there is some merit perhaps. Here, fuel dilution can be seen and there is no reason to think it would be much different at the first 7k mile OCI as one four cycles from now, presuming the use and environmental factors are similar. So if that is the goal, then that one characteristic can start to be tracked now. And by the way, I think 1% fuel for an EB at 7.5k miles is outstanding, overall. We've seen fuel in some UOAs up around 5%! To only be 1% is pretty darn good if you ask me for an EB engine. Perhaps being a 2013, Ford has tweaked the tune and made some changes? We'll not know until we see several more examples from a whole lot more '13 and later vehicles to make a decent conclusion.
Today's vehicle are extreme engineered for extreme cases. I doubt any harm has been done to this vehicle overall. Continued UOA trending will tell us if this is true or not, but my SWAG is that it's perfectly fine, despite the towing early on. If you've ever watched the Ford promo videos with Mike Rowe, and seen the abuse they heap upon this engine, you'll realize what he did certainly was not out of the ordinary, if only a bit early. But as long as he didn't tow heavily in the first 500 miles, he's probably fine. Even if he did do so, that would only make this an excellent test case against the pampered BITOG vehicles here.
I am a big fan of flushing all the break in fluids soon; engine, trans, diff, etc. But let's face it; we're mostly anal where the rest of the world trundles on past us with nary a thought, and yet their vehicles seem to last about as long as ours in the grand scheme of things. While it may not have been BITOG-approved to do what he did, I really see no harm coming from it. But ultimately time will tell.
I will note that this one FF UOA essentially has no value, other than knowing fuel dilution. If that's of value to him, so be it. It's a lot of money to find out just one thing this early. But that is my opinion based upon my wallet, not his.
