Many in the subaru community run this in their STI'S with great results. I believe the main issue is the higher ZDDP levels plugging catalytic converters, but that is a non issue for most of the tuned Subaru's out there.

Moly is bad for wet clutches I believe which would kill the JASO MA/MA2 certification of this oil
It is not JASO MA/MA2 rated anymore....just like its not API SN rated anymore either....had to do with the new CK-4 rating....I don't think the formulation really changed.

Last gallon I bought still had the JASO rating on the back. Are they making a hard switch to the CK-4 or will the other T6 still exist?

Nice, thanks for posting this up. Might start using this in the winter when I can't get Mobil ESP.
I've just sent over a current batch of T6 in the 15W-40 flavor to Blackstone last week, I'll be sure to post the results as soon as they arrive.

I'm running a 5w-30 HM oil now, but always have T6 on hand for other stuff . . .
I don't see any issues using this in a LS engine.

If you want to try Rotella T6 0w40 , it is CJ-4 SN.
