It's a shame that other retailers can't be a bit more competitive with the oil pricing, I don't need WM matched, but closer. It's just such a hassle to go there, and I prefer the "look" (as silly as it is) of an auto parts store receipt in my records. ha. Not AZ's though, they fade.
Sometimes other retailers are competitive, but it will be with oil filters that I don't want nor want showing on the receipt. Otherwise, it's that 1 or 2 time a year sale of Mobil 1 or another fine product approved for my car that I have to snap up. Always keeping my eye out!
Great find on the Valvoline MST product!
