...What I was trying to ask: is that why we see an oil like Amsoil, for example, whose CVT fluid covers a ton of manufacturer specs? Manufacturers seem pretty rigid on cvt specs, hence the large hesitation of people not wanting to move to aftermarket fluids.
Let get some language clarified. Amsoil and other Blenders are making a claim that their CVT fluid is "suitable" for
use in or can "cover" the various applications with this fluid in ....... vehicles.
Here is the exact Amsoil language:
"APPLICATIONS AMSOIL Synthetic CVT Fluid is recommended for belt- and chain-type continuously variable transmissions requiring the following: [LIST of Vehicles in which this fluid will function properly]."
https://amsoilcontent.com/ams/lit/databulletins/g3273.pdf
Why? Because of standardized testing such as:
"
Lab Tested
AMSOIL lab testing reveals AMSOIL CVT Fluid provides exceptional wear and durability for CVT transmissions:• In FZG wear testing (ASTM D5182) AMSOIL CVT Fluid surpassed a 12-stage pass.• In the JASO LVFA Anti-Shudder Durability Test, AMSOIL CVT Fluid lasted six times longer, translating into improved anti-shudder durability and reduced noise, vibration and harshness." This is only ONE set of tests that is made.
Redline has similar language here:

Valvoline CVT has similar language here as well under "
Recommended for the Following Applications:"
https://sharena21.springcm.com/Publ...2d889bd3/89a43c74-e29c-e711-9c10-ac162d889bd3
So why can Blenders make the "
Recommended for the Following Applications:" statements?
Because the additive manf. has thoroughly analyzed OEM fluids AND has done testing, such as described in the Amsoil 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DO NOT publish their fluid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. Fluid properties are not the fluid's specifications.
I don't know how much clearer an explanation I can present.
