Is the oil used for the 2021 K5 EX, and I would think all of the other models (Lx, LXS, GT-LINE and the GT),
a SEMI - SYNTHETIC OIL and NOT full synthetic (like MOBIL 1)?

Anything with 0w...is synthetic.

That's nice to know that (0W is synthetic). But that does not answer my question, "Is the oil used on my 2021 K5 EX
a SEMI -SYNTHETIC or NOT " ??

Just for reference, official Kia OEM 0w-20 oil is Mobil 1 Full Synth.

Part number: UM050-CH049

Why not just call the DEALER and see what they use in your model?

That is the first thing that I did. Matter of fact, I called them twice, the first time I was told SEMI - synthetic and the second time I was told FULL synthetic! Turns out after talking to a Kia rep. Semi was used in my K5. Finally, after 2 calls to the dealer, asking here on the K5 forum and talking to a Kia rep, I finally get a answer from someone that knows. It's SEMI - SYNTHETIC!! YEA!

Lol... Inconsistencies with the dealers are mind blowing. 🤯

You are so right! Good luck with your K5.
