BASF markets a formulation similiar to Toyota Pink? Doe this mean Valvoline makes the OEM fill for North American made cars like the Camry, Sienna, Tundra an d Corolla?

You are referring to:

"Glysantin G 70 OAT coolant, phosphate-containing"

shown in the Chart next to Toyota?

Wouldn't a phosphate containing OAT be an HOAT?

I wonder if this is, indeed, similar to the toyota formulation. Could it be "red" or "pink", though?

there really isn't much information.

Yes, it could be classed as HOAT since phosphate has a rapid affinity for bare aluminum and protects against corrosion. Phosphated OAT is used by Nissan and Honda, too. Essentially, only the marker dye colors differ. Does anyone know whether a G-70 is marketed in the U.S.?
