[NutmegCarrera]

I did the fluid on my 2011 outback a couple of years ago.
Was at 60k, and noticed a difference in smoothness after the change.
I used a redline product (there is a particular type that they recommend for the Subaru cat).
I did remove the pan to get as much out as possible.
It worked out to something like 6qts.
I bought 12 - so I'm all set for the next time.
Have gone about 28k since then. Still smooth.

Don't forget to do differential at the same time.
