I wonder what other things the OP doesn't bother changing like home furnace filters, coffee filter, toothbrush, maybe even his underwear. Lol. j/k
In "Part 1" I made a comment about my experience with European Factory filters disintegrating after a single oil chnge interval. A fellow tech was just telling me that GM's extended oil change intervals are resulting in their filter media also experiencing this disintegration and in some cases clogging up passages. Not to mention I have seen a lot of nasty filters (I wish I had pictures now...) as well as one or two that caused oil pressure issues and those that never did because they were always bypassed.
While I don't disagree with your point, it becomes a matter of common sense I think. At what point do you have to have experience running around naked in public before you can tell someone to put on a pair of pants in public for example?
So we shouldn't use oil filters at all? I mean they all can fail. Fram sells a lot of filters. It only makes sense that you will see more problems with them. I would be willing to bet they control at least 75% of the market share in sales in the DIY area. Usually the only place you hear negative comments are from people repeating false information from those that obsess a little too much about oil filters or the Amsoil crowd.
What's the bottom line? I read that super long post and he doesn't seem to say definitely what's what. I don't see a comparison table with results/scores.
everything = poop compared to OEM. even amsoil/RP
That's why I run Purolator filters.
While we're on the oil filter topic, let's show off a hugely detailed oil filter test with actual filtration testing:

Have to agree with the comment above, Fram isn't known for making quality filtering products; the bypass valve looks pretty crappy.
