Looking on subsequent responses, not much context on climate. Minneapolis in the Winter versus Phoenix in the Summer is quite a range for anyone to logically argue that a fixed multi-grade range is sufficient for adequate protection in these extreme environments. Using 0w-20 anywhere and everywhere ... Hmmmmm.

Why would anyone deviate from what Lexus recommends? They tested the vehicle in various climates from deserts to sufficiently cold places. If there were engine failures due to oil thickness, they would have change something. I'm just assuming the engineers that engineered, built and developed these vehicles would know what they are doing, most of the time, and what the vehicle needs.

As mentioned before in this post, 0w-20 is for CAFE...
The same engine is approved for 15w-40 for temps above 10F.
For my personal choice, I do not run a 20 weight oil in my two GXs because I want a higher level or protection during my 5k mile OCI.

On our 2019, I drained the factory oil and changed the filter at 109, 1764, 4849, and 7743 miles and did a UOA on each drain and fill and the wear numbers are down to normal levels at the 7743 drain.
The wear numbers even at the 1784 change were excellent compared to other engines
Your front and rear diff and TC are just as important as the engine IF you're going to be keeping this forever.
