Interesting enough, the body does not rust in Texas and I keep it parked at home and at work covered/no direct sunlight, so a Land Cruiser with a well running engine at high mileage in say 50 years could be quite a collectors item.

I would say consensus is a big word when discussing oil viscosity for our 3UR-FE... Seems indeed no MUD 200 owners run 15W40.
What I have learned from considering oil viscosity again and by reading up on Tundra forums is that high initial cold start rpm requires thinner oil at colder conditions. Considering start up and the way Toyota manages this points to 0W or 5W and not 15 or 20W. In order to meet your interest to increase viscosity at operating condition I can see using a 40, therefore 0W40 or 5W40.
Taking oil samples with the current oil you run and monitor the trends post a viscosity change would be an option to understand any improvement or adverse effects.
Another way is to use 5W30 and not worry about it anymore.

What I do not get from an engine wear perspective is why Toyota programmed the ECU to rev high at a cold start (initial at ~1500 and settlng at 1200 rpm, then a minutes later drops below 1000) other than cat heat up and again… emissions I would think.
My 535d inline 6 starts and revs immediately at 600 to 700, like many V8’s used to do as well. I wonder with the ECU tuning now possible (would have to search for the thread), this feature can be programmed out or maybe with a lower initial rev target.
