I am strongly STRONGLY against this type of filter. The job of a filter is first, and foremost, to filter. Run through bobistheoilguy.com and see all of the crap that gets by the filter (and shows up in oil analysis).
My opinion was recently validated by a professor of mine (now former professor) who calls them garbage... His credentials are many of years as an F1 engineer/machinist/crewman. I'm going to miss that class and his awesome stories
Besides, autospeed did a write up on pressure differential across the filter element... The dirtiest filter really showed no signs of pressure drop.
I inspect my filter - and replace when the rubber seal falls apart such that it won't seal. Oil analysis shows nominal silica - that's good enough for me
