There was a problem with fuel in the oil in early Ecoboost engines and that might be the case here. Maybe the PCV valve was good and then went bad.
If something like fuel or coolant is contaminating the oil who knows what will happen to the engine. Take it to the dealer and see what they say.
Lets say it gets fixed then I would get some cheap Supertech 5W30. Drive for a few hundred miles on it then change it out...drive another few hundred miles and change it again replacing it with a thick 5W30 like Pennzoil 5W30 Euro L or Delvac 5W40. Usually when things get into the oil they often linger on in trace quantities so I would do my own "flush" to make sure its gone.

Wish castrol made a 10w40 Magentec her win the states.
No uoa but at 5-6k the oil comes out water thin and may have the strongest smell of fuel I have ever smelled on used oil.
I don't think applies to mine since it's a 2018. I will get a uoa next oil change and see.
Thanks!
