It's definitely an odd move on Subaru's part. Maybe they'll offer a "w/ Moly" later on down the line as well...?
I'm most likely going with the Sustina, which I'm almost positive is the trimer type and over 100ppm. Probably a waste of money being I don't plan on any lengthy drains or driving it too hard, anyway. I'm sure any of the other top brands in the $6-8 a qt would be just as good, but I'm stubborn like that.
