Certainly a possibility, but I don't know the Ecoboost update history well enough to say. Eric might know.

New gets you factory warranty, so you may not have to financially deal with these type of issues, at least if you sell it before the warranty is up.
I'm allergic to spending New kind of money. So for me, it means there is more Due Diligence required on matters like these under discussion.
I'm not anti-DI (gasoline) per se. What this discussion reminds me of is that many of the newer technologies are very sensitive to the type of maintenance they receive, not just when it is done.
In other words.... choosing the wrong spec or viscosity grade of motor oil can have a bigger negative impact than on older engine technologies that might have been more forgiving.
As a parallel example, certain modern light-duty diesel engines (post 2007) can be very sensitive to the type of engine coolant used (re. heat transfer rate) - something that was much less of an issue with older diesels.

An example of fuel dilution, and OLM (Oil Life Monitoring) reductions with a GM platform.

Actual consumer use seems to have caused reductions in OLM settings for a few manufacturers.

The 3.5 ecoboosts seem to be better than some in the oil dilution issue. The worst problem motors IMO are the Hyundai DI four cylinders and the GM Ecotech DI motors. At 5000 miles it looks like I just drained a diesel.

I know that in the winter months, if I go the recommended 10,000 mile interval, that I'll be a quart or two over full. For a oil that's already very thin, this cuts it even further. The TSB doesn't really fix anything and would require you to always plug the truck in. Not practical. The better solution is to change the oil no more than 5,000 miles. There is a good chance that the oil dilution issue is what is leading to the timing chain and subsequent phaser issues with the engine. Ford's current approach is to defer until the vehicle is out of warranty. You don't want to be paying for this repair out of pocket because it's over 9 hours of labor!

When we bought all 3 of or F150 Ecoboost trucks, mine, my fathers, and my uncles we were all told by our dealer, Advantage Ford, not to go past 5K oil changes. The dealer supplied all maintenance for 36k so it was a non issue.
My father's and uncles are both still in that period. Mine has 61K and I have done all the oil changes after the 35K one done at the dealership. I have noted no oil consumption or diluting.

This ain't your older brother's MPFI !
There are a few curve balls here.....While I'm pretty sure I could still smell a large amount of fuel-in-oil contamination, I also know my sense of smell isn't what it used to be.... So I wouldn't personally count on being able to detect fuel contamination.
With my experience with Murphy, I know I'd probably end up with an engine that was burning 1.5 quarts at the same time it was making 1.5 quarts
For a DI gas engine that I was planning to keep long-term, I'd probably want to do a Used Oil Analysis now and then, esp. on models with known dilution issues.What is old is new again...... those of us who were changing oil in the 70's remember frequent oil changes....... carbs + old S* motor oil specs meant we had no choice. We seem to have moved the bar back down again........... what I find especially troubling with gas DI today is that the gasoline itself is now quite different...... notably added alcohol.
Gas engine motor oil definitely has very high demands put on it, by today's DI engines.

The HPFP is also internal so if there is a leak (I know of one), it will leak inside the engine. Turbo engines are kind of known for fuel in the oil anyways. Also, the very long (DOHC) timing chain had had some issue with wear and some think the oil dilution has something to do with it. Some are changing their oil every 3k miles with expensive oil to maybe prevent the chain wear. When the chain gets very loose, most will hear a cold start-up rattle for a couple seconds. The dealer will check for the code for the cams being out of time before repairing under warranty. For some, multiple repairs have not fixed it for long.
I also wonder if the reduction of ZDDP is a factor..... seen the front end of a Ford 5.4L apart..... those chains are scary long.
Not picking on Ford, I expect the others chains are similar..... As much as I like (short) cam chains, it's not hard to make an argument for timing belts in these applications.
