Managers, in fact no one at the store level controls prices. We have a spot for ours in 5 qt jugs, but have yet to get them in.Knowing Walmart it won't be that price for long. Once store managers realize that they can't keep this product in stock. There was only 3 5 quart jugs at the store I was at.
I'm guessing it's going to take a while before people find it, but how frequently will stores replenish stock is another question. If it's on Walmart's web page then maybe it's something they plan on keeping for a while. If I recall they used to carry a 5W-40 Mobil 1 diesel, but this is the first time I've seen true branded Dexos 2 in a non auto store.
You can get the rebate forms on Pennzoils website. They are hit and miss when filling these out, sometimes you have to hound them, but for potentially $12.97 for 5 quarts of diesel oil that's pretty good.
The 5W-30 full synthetic standard oil was gone.
