My 2012 Subaru Outback now has 170k miles on it and I am going to do a drain and fill on the CVT. Has anyone done this recently and could you please share what you used? I have heard that Subaru only sells the fluid in 5 gallon pails and that Amsoil CVT fluid or Valvoline CVT fluid are suitable approved fluids for use in the Subaru. Any opinions on this? Thanks
