If I remember right, Toyota LLC (Long Life Coolant), the red stuff, can also be used, but the drain interval is shorter.
I also seem to recall from my research that the Zerex stuff is made by Ashland, which is also Toyota's supplier. So it makes sense that it's now also being sold under the Valvoline brand. That's a good thing, as I recall having to go out of my way to obtain the Zerex Asian a few years ago. Had to go to NAPA to get it, as your regular Auto Zones and Advances, etc, didn't carry it back then. Maybe they do now.
Went into Advance Auto a couple of weeks ago. Haven't been in there for a while. They now started carrying the Zerex Asian. Zerex G-05 as well.
