For anyone who may also be wondering - i hope this helps.
I’ve been searching since purchase of my 2021 Subaru Crosstrek, for a compatible third party CVT Fluid that specifically states compatibility with Subaru’s CVTF-iii, as some TR580 transmissions spec for CVTF-ii and others spec CVTF-iii.
Sure, there are broad application fluids like Amsoil, Redline, Valvoline etc that claim compatibility. I have been seeking something more OEM spec oriented however, like Idemitsu SB2 for CVTF-ii, but they do not have a CVTF-iii variant.
I found while digging that ENEOS (Japan’s largest lubrication manufacturer and primary supplier of Japanese vehicle OEM fluids) has an Import line specifically made to meet OEM spec of Asian import vehicles, like Nissan, Subaru, Honda, etc. Their Model S line is for Subaru, and the product data sheet specifically states it is compatible with CVTF-ii and CVTF-iii. The bottle labels and packaging as well as main product page do not say this however, which led to some uncertainty.
I finally received a response from the company, and am pleased to make it clear for anyone else who has been searching for a better than “broad multivehicle CVTF” fluid for their Subaru CVT, that ENEOS Import Model S is fully compatible with Subaru CVTF-ii and iii. Please see the ENEOS response i received today. I’m sure this will be helpful when folks like myself over the years, search the web looking for something like Idemitsu SB2 provided for CVTF-ii when for so long there has been no specific CVTF-iii OEM Spec fluid available.

“AdkCedarMan,
Thank you for your patience. We apologize that we didn't get back you sooner.
Regarding your inquiry about the compatibility, thank you for bringing this to our attention. We appreciate you taking the time to point this out.
We apologize for any confusion or inconvenience caused by the outdated documentation.
The formulation of Import CVT Fluid Model S has not changed. The product has always been formulated to be compatible with Subaru CVTF-III (Lineartronic III), and we have been selling the same formulation throughout.
The recent update was made to the Product Data Sheet only. The documentation had not been updated to reflect the full compatibility of the product, and the revised PDS now clarifies compatibility with Subaru CVTF-III.
Likewise, the bottle label has not yet been updated and therefore still references CVTF-II only. This is a documentation and labeling update rather than a change to the product itself.
Since there has been no formulation change, there is no manufacturing date or batch code that distinguishes a "CVTF-III-compatible" version from earlier production. All production of Import CVT Fluid Model S has been manufactured using the same formulation and is compatible with Subaru CVTF-III.
Regarding part numbers 3074-300 and 3074-301, they contain the same formulation. The difference between these part numbers is related to the SKU, -300 represents 1 qt bottle, while -301 represents 1 case (1qt*12).
Thank you for your understanding. Please let me know if you have any questions.
