Looking at the VOAs of DS, it still looks to have one of the more robust add packs going for OTC conventionals and at Wal-Mart it's cheaper than both PYB and Castrol GTX. (over 150 ppm moly, over 50 ppm boron: http://www.bobistheoilguy.com/forums/ubb...rue#Post918545)
The 5qt containers even come with seal, which I like.
