No, there's a good handful around the world, and there were multiple different oils by different manufacturers through the history of TGMO even in the US, one of them being not particularly shear stable, in one study that I've seen losing 7-8% of it's HTHS in 400 miles.
But that being said, CATERHAM in his studies, assures us that all of the TGMO variants, in spite of their quite different make-ups were all designed specifically for your Toyota (regardless of engine family, displacement, or platform)
