I believe that means you can run it every other change.
You need to remember that in 2010, 0W-20 was pretty rare.
Also, with virtually the same viscosities, how does the engine discern a 0W-20 synthetic from a 5W-20 dino?
Toyota's 0W-20 choice in the US is driven by our CAFE standards, not the engine's requirements.
5w30 would be in the manual if it wasn't for fuel economy concerns.

Do you have proof that 5w30 would be used if CAFE wasn't standard?
