5W-30 for hot climates? 0W-20 for cold climates?

[127.0.0.1]

the oil pump is variable
the oil is used as hydraulic fluid for actuating VVT

regions have different ECU programming for 0-20 where 0-20 is specified
programming is different where 5-30 is specified

imho use what your manual says to use

If 5W-30 is used as the standard oil in other parts of the world, it obviously was designed for it.

How do you know that everything about that engine, the supporting components & the software programming is EXACTLY the same from country to country. The same parts numbers are not enough proof that it's the same exact engine & such.

T24A-FTS was definitely designed with 0W-20 in mind given that even in the UAE, the Prado is factory filled with 0W-20. That said, they allow higher viscosities despite defaulting to 0W-20. The idea that it's a US-only phenomenon is false.

So say live in Alasaka and that is where you bought your 4Runner. But then you move to Phoenix, Arizona taking your bought in Alaska 4Runner with you.

Are you going to go to your friendly Phoenix Toyota dealership and ask for the hot climate ECU programming? What do you think their reaction will be?

your post makes no sense whatsoever
but still no, Toyota can't convert a US spec
vehicle to GCC

How does it make no sense? If the ECU programming is different depending on regions, that would mean it needs to be changed if you change regions.

If it does not need to be changed, then why have different programming? Remember the discussion is about oil viscosity and oil pumps being variable.

I do find the suggestion that the ECU must be programmed to a specific viscosity to be suspect, given the aforementioned Prado using this engine in the UAE allows for multiple viscosity options, including 0W-20. If it’s so sensitive that it only works with 0W-20 in the US, how is it able to handle multiple options elsewhere without reprogramming!

That said, I don’t see a reason to run anything other than 0W-20 myself. But I live in the PNW, not Phoenix. Though I grew up there!
