I guess you'd have to reach out to Dave.
Thanks - that seems to be the ticket!

So let's define say, an ATF fluid's SPECIFICATION:
A fluid specification may define the following items (this is not all-inclusive):
1) the necessary (and many) ASTM and industry-defined standard testing to determine friction durability, viscosity retention, dynamic friction coefficient Mu(v), wear of gears and clutches and belts and pulleys,
2) the fluid's viscosity in terms of 40C, 100C, and Brookfield viscosity,
3) pour point, flash point, etc.,
4) rust and corrosion inhibition, metal inhibition, and foam inhibition.
So why can Blenders make the "Recommended for the Following Applications:" statements?
Because the additive manf. has thoroughly analyzed OEM fluids AND have done testing, such as described in the Blender's literature, to safely make those claims, tests that are industry standards for North American and Asian transmission manf.
Again, and as I have stated before, Asian transmission manf. DO NOT publish their fluid specifications. So if I, an additive manf. develop a replacement fluid, I have to test it in actual hardware and in a balanced formulation using tests such as the FZG wear test (ASTM D5182) and the JASO LVFA Anti-Shudder Durability Test.
The only thing you will see listed from a blender's Technical Data Sheet (TDS) is the fluid's properties and its Recommended for the Following Applications list.
Fluid properties are not the fluid's specifications.
So im assuming its safe to say that Amsoil, HPL, Valvoline, Castrol etc.. has their own CVT fluid that is “Recommended for the following applications” it’s ok to use even though it isn’t oem
Okay - I used the wrong word. After some further reading and consideration I purchased four quarts of Idemitsu CVTF Type H2 via my nearest NAPA store. This will be a project for another day; need to complete the snow swap and oil change on the Prius V first.
