A few years ago I went around looking at "store brand" conventionals and discovered that NAPA, O'Reilly, Pep Boys, and one other (can't remember which one) were ALL bottled by Old World Industries, the parent company of Peak. I think Peak just about has the whole conventional AF market cornered through their own brand and by bottling store brand antifreezes. Zerex makes one, but darned if I can find it anywhere. Even places that have shelves loaded with Zerex's DexClone and G-05 don't seem to carry the Zerex brand conventional very regularly.
