After a few hours of research, I learned that the SuperTech filters were made to Wal-Mart specifications by Champion, and depending on where youre from, the Wal Mart oil is made by WPP (most of the country), Quaker State (the south and west), or SuperKleen (Canada).
The disadvantage to SuperTech filters are less surface area and a 'digital' bypass valve, which is either completely open or closed instead of opening gradually -- 'analog'. The 'digital' type gets the job done, but the standard 'analog' type is apparently better at filtering throughout the RPM range.The low-end Fram filter has the same issues except its VERY poorly constructed, using a cardboard end plate inside attached with some crappy glue.
The SuperTechs also seem to provide good flow and efficiency, much better than Fram. Of course, the Fram XG is better than the SuperTech, but thats a $10 filter.
For $2, you simply cannot find a better oil filter value -- you cant! Just replace every 3-4k. Wix/Napa filters are supposed to be pretty gosh darn good, but I cant find a nearby supplier here.
But if you're running something like Amsoil for 10k then, of course, you can justify the expense for an Amsoil or Mobil 1 filter.
