I think it is specifying it directly. I don't know of any
multi-viscosity organic oils with "0" as their lowest viscosity.

Googled this up:

If I read this correctly, 0W is about twice as viscous as cold water:

You'll want to avoid non-API certified oils at all costs, and that
includes most Amsoil products.

You can see a list of all the 0W-20 oils able to meet the API standards
at "http://eolcs.api.org/FindBrandByViscosity.asp?Viscosity=0W-20".

In general, Amsoil products cannot meet the API standards because the
level of phosphorus is too high. The API, and vehicle manufacturers,
have determined that high levels of phosphorus will cause early
catalytic converter failure.

For what outside temperature range?

That seems incredible; only place I've ever heard of that range would be
in Arctic-like climate/temperatures.

The only reason for it I can think of otherwise is its how they managed
to get mileage ratings boost by lowering oil viscosity so much.

Tried to get to an owners' manual online; stinkin' Toyota site wouldn't
let one at it w/o "registering"--what's up w/ that just to look at a
publication??? :( Anyway, wasn't able to check on what the
recommendations are or alternatives, sorry.

I'd surely do some more checking though...

The only two viscosity ranges mentioned in the owner's manual is 0W20
and 5W20. Surprised the hell out of me when I saw that.
