Amsoil ATF?
 

Has anyone been using Amsoil or other synthetic ATF in their auto tranny RX8? I have had good results with this in the past and wanted to get some opinions before I used it in my RX8. Thanks for your comments! I could not pull up any good info on a search. :(

i can't really comment on this 'cause i don't know what type of ATF fluid the unit uses, and the varities produced by Amsoil.

read your owner's manual, and check out products by Lucas and Redline as well (very similar competitors) if Amsoil doesn't have what you want.

i used redline for both tranny and diff. very smooth!
