I was shopping for motor oil this afternoon and I noticed something weird. The jugs of regular Mobil 1 (all weights)were in their usual prime space just like normal. I did notice that the price for a five quart jug had gone from $21 up to $23 and change. I just figured that it was a typical price increase. The EP was still $28 as far as I remember. The funny thing was that I walked down the oil aisle, hung a left, and there was another shelf display of regular Mobil 1 priced at $21. Anybody else encounter this situation at their Wal Mart?
