I got curious and asked them, since Mobil 1 ATF used to say ATF-Z1 on it, but doesn't anymore.
This is what I got:
Me:
Hello, I have been using Mobil 1 Synthetic ATF in my Honda. I notice that it no longer lists Honda, Toyota, or Subaru as applications where it can be used. Is Mobil 1 no longer recommended for Honda applications?
Mobil:
What is your transmission fluid requirement?
Me:
ATF-Z1
Mobil:
Mobil does not have a suitable product.
