Since 2015 there have been improvements that reduce oil contamination of the intake valves which was the biggest issue for valve carbon build up. The intake charge pipe was soaked in oil as you can see from the pictures below, and so was the IM and throttle body. Here’s another example… So, DI good… valve coking bad! NO oil is ever beneficial in the intake air charge....oil causes detonation, slows and disrupts the burn pattern and flame front as well as the deposits affect quench.

As suggested by @HayaiKuruma, so far the 'valve coking' issue associated with some DI engines does not seem to be a prevalent problem with the 'original' 2.0 EcoBoost specifically (i.e. I know the 3.5 underwent a rework in 2017 but considering they knew about the issue several years prior that seems like a long time to go before making the fix. Now, for those who don't know, valve coking is what occurs without a traditional port injector present to essentially clean off the backside of those valves, and again happens on direct-injected applications. Valve Coking. The concern with valve coking (carbon deposits from burned oil) is from vaporised oil in the intake stream coming in from the PCV system, that is why oil separators ("catch cans") are inline on the PCV hose that feeds to the intake. … The main benefits of the RX, Tracy Lewis Signature series PCV air/oil separation crankcase evacuation systems over most “catchcans” are as follows: 95% plus effectiveness at stopping and retaining all oil and other … Developed products for solving direct injection intake valve coking issues.
