Stick with Kirkland excellent value oil. There are many things better for cheaper in the world, some of them are Costco engine oil, hotdog, and rotisserie chicken.
Don't waste your money on marketing cost of premium oil that cost 2x, but perform 0.9- 1.0009 better in most cases. Unlike you do racing or crazy stuff, PAO base oil may benefit you. Just do 5-10k miles interval and have 1 million miles good run.

There are various 508/509 oil that mainlyb group 3 these days like Ravenol VSH, 90% HC, but also PAO Ravenol VSE. Both are rated 20k miles, but PAO VSE was born first. Group 3 oil can be as good as PAO for certain application, including VW demands.

I had a 2016 CX-5 with the 2.5L SkyActive engine. Car got totaled at 155k but the engine was spotless and ran great. Used 0W-20 most of its life but switched to 5W-30 at around 110k.

This engine is GDI and is a bit prone to fuel dilution, especially if you do short trips. My wife did and UOA's showed fuel dilution. If you tend to do short trips keep the OCI's short-ish. No more than 5k miles.

If I recall the owners manual stated 0W-20 for North America for fuel economy purposes only. For the rest of the world it recommended 5W-30.

Any quality synthetic will be just fine for this motor. They aren't prone to deposits unless abused and neglected.

Then after a couple OCI's, change to this: https://www.amsoil.com/p/amsoil-signature-series-0w-20-100-synthetic-motor-oil-asm/?zo=515729

Thanks!

Why start with OE and then transition to SS?

Short OCI, less cost, API

Why does API matter early but not later?

Very very improbable possible Infant mortality hassles which are not reality just moral support for the owner.

Lol "infant mortality" = early engine death?
