The last few times I was in my local store, Quaker State Ultimate Durability was nowhere to be found. There was not even a place for it on the shelf anymore. I asked a worker and of course he did not know anything about anything. Then tonight I happen to browse the clearance aisle and find 2 5qt jugs on the bottom shelf along with various chinese junk with red price stickers. I think the price was still $19.53. I then went to another walmart a little farther away and they are still stocked with it! Anybody know what might be up? I thought maybe it wasnt a huge seller and they may be phasing it out. Why would one store have it and not the other?
