I don't doubt that Toyota is moving to 20 weight as the industry trend has been to 5W20, and now 0W20 motor oils. But I don't think the TSB applies to the 1NZ-FE engine which is one of the oldest designed engines you can buy in a current Toyota and is in the process of being replaced by the NR engine family.

Tell us more about this NR engine. Whats it used in? And we need your sources!

Like alanwagen posted I used wikipedia and club-toyota.net. There's also a really good summary of the various Toyota engine families since the 80's/90's on club-toyota.net.
