OEM quality
This stuff is supposed to be as good or better than OEM Subaru CVT fluid. It works well so far. And it's definitely a lot cheaper than taking it to a dealership and having a flush and fill done

A much more affordable option for Subaru owners
When you're paying between $16 & $18+ per quart of Subaru brand CVTF 2 fluid this is a much more affordable option. If you look on the back of a Subaru branded CVTF 2 quart bottle you'll see the Idemitsu logo. Doing this job myself saved me over $1000 on what the dealership quoted me to change the valve body and drain and fill my CVT without skimping on anything.

ATF OEM product that works
Since Idemitsu is the OEM of Subaru’s CVTF-II ATF, it gave me confidence to give it a try. I’ve used this on my 2019 Subaru Outback at 130k+ miles. One month in it has been running fine.

Noticeable Improvement after Replacement
Replaced a Subaru CVT transmission fluid with this product, you can tell the car drives smoother after the replacement. Would recommend for Subaru drivers.

Works great, replaced old CVT fluids in Forester by circulating & draining twice. Hope it becomes available again.
