Updated: 2/14/14 still more to add. anyone with information please post and I'll update #1st post :tup:
I'll need to add more when I get home, I'll be very busy this week. I'm thinking about adding what capacity/specs fluid each year uses, as well as the torque specs of each.
Updated: 2/25/14 Added AMSOIL's recommendations, along with Capacities and Torque specs of each. 2014 STi's and up do not have any information on AMSOIL's site.

Updated: 2/14/14 still more to add. anyone with information please post and I'll update #1st post :tup:
I'll need to add more when I get home, I'll be very busy this week. I'm thinking about adding what capacity/specs fluid each year uses, as well as the torque specs of each.
Updated: 2/25/14 Added AMSOIL's recommendations, along with Capacities and Torque specs of each. 2014 STi's and up do not have any information on AMSOIL's site.
