I have had a Mann OF in my car for the last oil change. The oring it came with has always leaked a little. Prior to that I had a bosch OF...oring never leaked. Changed oil today and installed a Hengst filter with the oring it came with. Hengst oring was noticeably thicker than Mann. Anyone else notice this?

No, I have not experienced this with any of the filters I've used, Bosch, Hengst, Mann, or Purolator.

I would have expected this from napa, but I thought Mann was pretty decent stuff.

So far, only the Carquest filter ( adn I'll never bother those guys again, its a pita for them to get MBz parts), had a sloppy oring. Too big. Had to reuse the old. That one was " made in Poland", if it matters.
