The pics that Neil posted pretty much say it all but mainly (in my order of Fram disgust)
1) The cardboard end caps
2) The lame filter media
3) A very questionable bypass valve

Years ago the Checker, Schucks, Kragen chain sold them for $2.99. On Sale they were $1.99. Fram built itself a decent reputation back in the 60's and 70's (and did an outstanding job of product identification/marketing with the orange)with fairly acceptable quality then cheapend the product in the worst possible ways in the 80's while enjoying widespread consumer acceptance. They sell mega millions of these POS's.

I stopped using them in the 90's. In Hindsight I would have stopped sooner, but I guess I got away with it (sold cars before any oil or filter related failures).
