Definitely old stock. There's a lot of it up here in Canada. If you look on the back though, it might say SL formulation on it, in which case it's the in between version between SJ Trisynthetic and the SuperSyn. This version of TriSynthetic has moly in it, and showed pretty good results in my sister's car.
Heck, at my local Walmart they've still got a few bottles of the very old Advanced Formula Mobil 1! (in 15w50, which isn't a big seller around here)
