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.
Toyota super long life is the pink coolant. Zerex asian is more like the toyota red stuff. When it leaks and dries it doesn't crust up like the pink stuff.
Believe me, it's the exact same stuff. Zerex Asian = Toyota SLLC. Toyota even has a deal with Ashland to supply it to their dealers. I remember from my research on it a few years ago.
It's 10-year, 150K coolant.
The crystals around the overflow on my Taco right now are even pink!
