Can we use a different brand of ATF other than Honda ATF w/ Z1? Like the one from Mobil, Castrol or any other brands...I read the manual that it says any tranny fluid as long as its dexron III or better.thanks guys.

 

Honda or Amsoil tranny fluid. No others. You might want to re-read the Owner's Manual. It mentions Dex III, but it also mentions only using it in an emergency and draining it out later.
