For reasons I've never seen confirmed, but are bandied about on the internaweb continually, FRAM filters are the hideous boogiemen in the closet of automotive accessories. I've been at this for hard against forty years, and have yet to have any first-hand, or meet anyone who has had an issue with FRAM, or any other filter. But then, my wrenching reaches back to days that engines with no filtering (VWs, Chevrolet pickups) were not uncommon, and the vaunted toilet-paper-roll filter was. I've seen one filter fail, when a friend blew a Motorcraft oil filter off the remote mount of a Mangusta. It was caused by a cocked and seized bypass valve.
Ah, but Pennzoil will dissolve the aluminum parts of your engine, too. So they say.
WIX have an excellent reputation for filtering.
Another thing not considered by the worldwide motoring public is that a "dirty" filter does a better job of filtering than a new one, which is why your owner's manual says to change it at every other oil change. But these are the folks who don't think about how much of their oil is going through the bypass instead of the filter during regular duty.
Once oil has anything large enough in it for a filter to remove, the engine's done for anyhow.
