I have used 5W30 in my 4Runner for a couple of years. Summers here in TX are hot and winter is not usually that cold, you can work outside in shorts in shorts in December, usually. I use 5W40 in my other two cars, one gas and one diesel. Has anyone used a 5W40 in a Toyota engine that is spec'd for 5w20 in the USA and 5w30 every where else?
Has anyone ever used 5W40 Euro in 4Runner.

I don't know if you have a 5th gen, but the Dual VVT-i 1GR-FE is speced for 0w20 in the USA, and ranging up to 20w50 in some markets in an appropriate ambient temperature range.
5w40 won't be a problem.
15w40 in a 2010 Yaris and two 2013 Matrix.
SAE 40 in the Yaris one summer with #3600 filter.
Where space allows, a ph8a size filter can be substituted. We used those on 22R Toyota engines.

If you care to search there are likely 50 existing threads on using a higher grade than what the manual recommends. Perhaps more.
I previously ran M1 FS 0w40 in my 2018 4Runner before switching to Valvoline EP 5w30 simply because I had some left over.
Will be switching back to the M1 0w40 on the next oil change.

I’ll guess two a week for the last 23 years.
I always wonder why people need to ask this question.. The thicker the oil is the better until it is too thick. With proper maintenance and luck the Engines usually out last the transmissions and chassis.

Generally speaking though, there isn’t really much benefit going up by two grades though. If it calls for a 0w20 and you’re wanting to go thicker, your typical 5w30 with an HTHS of around 3.1 is likely all you need. And if you still want a bit more, then choosing one of the Euro 5w30s that have a 3.5 HTHS should be more than enough. Anything above that really isn’t necessary. I just don’t see the need to use any of the 40 weights for any car that originally came with 0w20, unless it’s being used for racing. It’s just overkill for the street IMO.
What…is…your…oil…temperature?
I don’t really care how hot it gets outside in Texas - your 4 Runner has an oil cooler. So, your oil is not getting as hot as you seem to think it is in that Texas heat - it is better able to cope because of the built in cooling of that oil cooler.
So, what is your actual oil temperature?

I run Mobil1 0w40 in my 2015 Sienna and my 2016 Prius.
Post ‘em. Come on - respect the game.
4.0 can use up to a 50 grade overseas. So a 40 would be great.
Will be going 0w40 in my '13 FJ next change myself; been on 5w30 until now.

The oil temp question is a good one, that I don't know the answer to. I also have a 23 Jeep with the EcoDiesel that I can see the oil temp and trans temp as I drive. The 4Runner is a 2020, 2wd, with 45K miles on it. If it has an oil temp display in the info screen, I have not come across it. Not saying it is not there, I just have not observed it.
Sadly, I know of no Toyota with an oil temp sensor. Oil temp sensor is one of the most eye opening, and useful gauges, yet almost no manufacturer besides VWAG puts one in.
So, in the absence of that information, we are guessing.
It’s OK.
And in alignment with the owners manual on extreme operating conditions, you can go up to a higher viscosity.
That’s what I’ve done with mine. Followed the owners manual.
But don’t just assume that because Texas is hot, you need a higher viscosity oil - that’s a big “maybe”.
