gsxr and the performance guys prefer Redline Dex II (labeled Synthetic ATF) over the other Redline ATF formulations (D4, D6, etc. which are also synthetic).

Mobil 1 ATF might or might not be good stuff but it's discouraging that product labeling keeps changing while website information doesn't. I'm running Mobil 1 ATF without issue now but I will choose something else if they don't reconcile package and website or at least answer the two messages I've sent.
