Not All Tellurides Have the Same Engines

[TelLX]

.... Or so it seems.
I have a 2021, and the Owners Manual shows oil capacity as 6.87 US qt. (6.5 l).
But according to the 2023 Manual it's 7.08 US qt. ( (6.7 L).
There are a number of other differences as well, including when to check oil level (5 minutes after shutting off engine vs. 15 minutes), and maintenance times/mileage.
If it's the same engine, why the different spec's for different model years?

I remember seeing Youtube review of newer Palisade, and one of its selling point was a newer, bigger engine.

Forget what I said. I remember seeing this video (its in Korean), and it says nothing about changes in engine. It does highlight Hyundai making changes to the frame to account for the new side collision standard, improving the wheel housing noise insulation, better shock and spring components, new torque converter to address low speed transmission vibration, etc. I'm guessing similar improvements went in to the newer Tellurides.
