Dealer oil fill 5W-30 - UOA from engine (G4KJ) Kia Sorento '18

Aside from detecting problems with leaking injectors, poor air filtration, or a coolant leak into the oil not much else can be determined from a UOA on such a new engine.

I'm not a fan of dealer bulk oil for the reasons already mentioned.

Your conclusions are wrong, you just don't know how to read UOA and draw parallels and draw the appropriate conclusion.

Yes, yes - we know these insinuations. That it is better to use SAE 50 oil for these engines and that SAE 40 can have an unpredictable wear effect, and using SAE 20 generally resembles flirting with a policeman with a knife in your hand (there are not many variants).
