I like this part:
“And finally,” said Nuñez, “Reliability comes with respected brands. Since most motorists and even professional technicians don’t normally cut open filters to examine their materials and construction, you’ve got to rely on manufacturers who stake their decades of reputation on the design, construction, and performance of components, materials, and engineering that, for the most part, go unseen once they’re assembled. ....blah, blah, blah, propaganda.....”[/i]
Thats what saves Purolator's rear end, the fact that most oil filters are spin-on and hide their failures. We need a law passed making all future engines use cartridges only, then you won't see these media ripping open.
