You can't buy anything but Fram filters at Kmart, now that Penske and Castrol have been phased out. Fram seems to be taking over at WalMart too, with SuperTech going the way of the edsel. I just hope they keep stocking Motorcrafts for only $2.77. Whats the deal? Where can you buy Penske or Castrol filters now? Ive got PepBoys, AutoZone, and Napa here to get filters at, but no Kragen, Shucks, Checkers, Murrays. Ive never even heard of those places. What's happening to the filter market?
