Mahle OC 261 from my French spec Land Rover 90 (Defender before they were called Defenders), 2.5NA diesel. Thirteen months and ~1,300 miles w/ M1 5w-50.
Very well made filter, heavy can, heavy tube and end plates, even pleats, glued and crimped, rubber gasket on the bypass valve. COO Austria. Nothing beyond some carbon particles in the pleats.
