Pretty sure 99% of the problems people are having with torn filters are user error. Purolator clearly states to only use the Classic and P1 at factory recommended OCI intervals. Which, for most cars is still 3k to 5k miles. Neither filter is marketed as an extended drain filter, and the majority of the tearing issues are happening to filters used beyond the recommended OCI or longer than 3 to 6 months. The media is just like paper dunked in a glass of water, the longer it stays saturated in oil, the faster it breaks down and is more susceptible to tearing.
I'm not saying it's okay for a filter to tear, but it's also not okay to push it beyond it's recommended usage interval and blame the manufacturer because it failed. I don't think Purolator should be getting away with these quality control issues and I, like many others hope they get their ducks in a row one of these days!
Your theory is not true. Many of the torn filters reported had normal OCI mileage on them. And keep in mind that all of a sudden there was a big rash of reported torn Purolators. It wasn't because everyone all of a sudden started using them differently, it was because something changed in the manufacturing and quality of the filters. Pretty easy to see that.
I take it you never saw the infamous "tear spreadsheet", which BTW should have about 25~30 more filters listed that aren't because Stu_Rock stopped keeping it up to date. Take a look at use mileage column and you'll see most of these were not really ran very long.
