I'm curious, has anyone ever scientifically tested the flow difference on a used oil filter as compared to a new oil filter, to see how much flow is actually affected after 5k or 10k miles?
I've read so many threads about guys complaining about "bad" oil filters but have never seen any testing data. I look at all the cut open filters filtering media pictures & can NOT see any evidence of a clogged-up filter. It would be nice to see some flow data after different miles of filtering oil.
