Thought I would post this here for anyone interested. Here is Results from Blackstone for the Toyota ATF WS taken from my 2013 Prius V. I wrote the wrong mileage on the sample I sent in, it should have been 65300. I'm the second owner but I think this is the original fluid, when I pulled the plugs it didn't look like they had been removed before.
Hi dyethor, I shamelessly posted your UOA to the Gen 3 forum last Thursday. interesting transaxle fluid UOA from BITOG | PriusChat
