Gas Direct Injection & Oil Change Interval
I have run a couple of Blackstone reports on my oil from the truck in my signature. No issues, metals look fine, but the fuel dilution is up to 2.3% and there is a related drop in viscosity at 5,000 m...

I seem to recall that ford is/was having some issues with fuel dilution in the oil on some ecoboosts.
That does sound high. On my 04.5 duramax at 10K miles blackstone shows no fuel dilution, same on my 97 Mercedes E420 at 7500 miles and my 97 Mercedes SL500 at 7500 miles.
With fuel injection fuel dilution shouldn't be an issue anymore. You might want to do some checking on possible TSB's from ford on the ecoboost for this.
DI engines in theory should have less of an issue with fuel dilution than any other injection since fuel is metered into each cylinder individually. Even port injections can have fuel cross flowing between cylinders since the fuel is going to the intake manifold. so cylinders could be running rich or lean under certain conditions. And since it is high pressure it vaporizes quickly as well.
