When I lived in Nashville I saw HUGE mountain of blowed up cummins motors that could not be disposed of because they were part of a lawsuit against Fram, the guy there said at least %90and (probably higher than that) of the blow up cummins had Fram fiters on them when they would show up for warranty reasons. I personally worked at Wal-mart as a teen and cut open a lot of oil filters when I was bored and the Fram filters were worse than no filter at all, pieces of the card-board ends would fall apart inside of them, sometimes you could shake them and pieces of the filter media or ends would just fall out. Wal-mart here stopped doing oil changes because they had to buy so many engines.
