I always thought the Fram filter issues where just stories 'till I saw one situation first hand.
The story: about 10 or 15 years ago, Dad changed his oil in his Jeep Cherokee and used a Fram filter. He ran it and checked for leaks afterward - no problems. Parked it until Monday morning when he got in to drive to work. He made it about 15 miles before it started rattling like there was no oil in the engine and he pulled over / shut it down. He checked the level and it was good. He grabbed the oil filter and unscrewed it 1/4 turn and it blew oil out under pressure. It seemed as though it failed internally, completely blocking the flow of oil. Towed it home and tried a new filter only to find the engine barely running and making death noises. When we asked around a few places about this, everyone said "You used a Fram filter, didn't you?" Too bad...can't prove anything for any sort of warranty, so I got to put a new engine in the Jeep in a cold barn workshop in the middle of February....no more Fram products in our family.
