2) Is there current evidence that the Purolator filters are still having tear problems? Wasn't the tearing problem an issue prior to 2015 when Purolator introduced the Purolator Boss line and may have also made improvements to their other two filters, the Classic (red) and Pure One (blue)? What about recent Motorcraft tears?
3) Are cellulose filters prone to develop moisture in the media that could possibly contaminate the oil? Is that a known issue with this type of media? Are synthetic/blend or full synthetic media filters better in this regard?
1) Depends on how clean your engine is and your driving style. I'd run a cellulose filter to 10K if most of my driving was long highway trips and my engine was nice and clean inside. Probably not go that far if lots of short city driving trips - more like 5K~6K.
2) No, see the link in my post above of Motorcraft filter made Feb 22, 2017 with tears used under gentle conditions. And there have been other Purolator made filters reported torn hear recently. You just don't see as many because 80~90% of the people who use to buy them just don't anymore.
3) No, but they can absorb some moisture that's in the oil if you're short tripping the drives. If you're driving you car pretty far at a time (like 30+ minutes) and the oil gets to full operating temperature for awhile then moisture in the crankcase will burn off and get sucked out via the PCV system. Nothing to worry about, and shouldn't be a reason to chose on filter over another.
