Former ST user here, but may go back. Long before BITOG, I decided I liked the looks of an ST insides better than a Fram PH 3950. Used them for years until they dropped them a couple of years ago. Champ seems to have gone Ecore for the larger filters and the button DOME end and conventional construction for the smaller ones. I might try the ST 3593A they now suggest if it had a thread end bypass. I looked for an oversize, but as far as I can tell, the 3593 is the only 20 mm thread filter my wal-Mart stocks.
Been making due with Purolators, L10193, dome end bypass and much less media than the ST 3950. What does my extra buck over an ST3593A get me, but enriching a foreign owned company?
Next oil change I am looking at STP, Hastings, or Pronto.
