Went to the two local Walmarts within a 25 mile radius of my house today to try and get the PL30001 filter for my Ram in signature. Both Walmarts have no classics but in there place are now Super Tech Oil Filters. Which before neither Walmart for years had them. Who makes Super Tech oil filters these days? The filters they do still stock are Motorcraft, HUGE selection of Frams, Super Tech, K&N and Bosh. They also did away with the Mopar filters.
