Every Wal Mart around me has Mobil 1 AP, and it isn't on clearance. It has been available for awhile, so I'm guessing it must be doing ok. Wal Mart doesn't stick with something very long if it isn't moving, and corporate would know better than a stock boy. I guess we stay tuned to see what happens. I went into Autozone today, and they did not have AP. They did have the new HM EP, though.
