To throw a monkey wrench into the discussion, I've started using the overseas manual to select my oil grade. [insert CAFE discussion here as to why only 0w-20 is recommended in the US; I don't want to clutter the thread]
For my model year, Toyota's 4Runner motor oil charts in Australia look like this:
The upshot of this is that I'm currently using 5w-30 for the winter, and may move to a 0w-40 or even a 10w-40 next summer. Don't know about using 15w-40, that's a bit thick for me but in high summer....
The engine doesn't have different parts if it's in the US, Australia, Asia or Europe. It's the same engine, same oiling system, same bearings, etc.
I got a great UOA using 5w-20 while towing last summer, but I'm testing the 5w-30 to see if it does better on the UOA. Including the 5w-20 UOA below for reference.
Currently using Amsoil, but likely changing to Schaeffer's once my stockpile is used up.

Fantastic UOA; if that was my report I would not change a thing. That Amsoil is serving you Very well; I’ve been using Amsoil since 2013 when I was canyon racing in the mountains. Racing up the side of a mountain every weekend for hours then daily driving to work for 5k miles and my blackstone UOA’s were perfect. I really like the Gear oil as well! There are only a few group 4 and 5 base oils on the market and Amsoil is one of them. They have a very good product, especially if you prefer long drain intervals.
I think a 40 weight oil is to heavy imo but I’m seriously considering 0w30. You make a Very good point, in other countries most vehicles are using a thicker oil per the manual. This rise in 20 weight oil is CAFE requirements, plain and simple imo. But the flip side to this light oil generation is the attention to formulation and additives; a good example is your UOA.
If you bump up in weight please let us know how is goes and what oil and weight you choose.
