Low filtering material and crappy bypass is what I remember being the main reason for their shittyness. I never had any problem with my Frams but I don't want to take a chance with something that will cost me 1-2k dollars to rebuild an engine if my oil filter explodes or fails. I normally use Bosch or MAZDA filter. MAZDA filters have about twice as much filter material in them as the fram ones. Thats one big *** difference. The mazda filters are like 5 dollars. Its worth getting them so why be a cheap bastard?
Fram filter...when get clogged up can let oil bypass the filter cause your oil to get dirty quick. some people have problems and some people dont. Its one of those thing were if it works for you...then its good to use for you. if it doesnt work for someone else then they go try something else
ive always used fram filters but i think i will start getting mazda filters. it seems the fram does a good job at cleaning the oil for about 2000 miles then the oil starts to get pretty dirty, i do notice a big difference between oil at 2000 miles and 3000+ miles. obviously im no mad scientist but ive concluded that its prolly best to get oem mazda ones.
On the cars that we race regularly, a couple of 1982 Tiga Sports 2000 cars, we use fram oil filters, but not the sure grip. Aparently, and don't ask why, because we don't know either, since the sure grip is an outer coating, through many race weekends and much cleaning up after it, the suregrip on the filter leaks. This dosen't make much sense, but that is just what we have found out. come to your own conclusion...

I havent used Fram filters before, but I did oil changes on people's cars I ended up breaking the filters in half when pulling them off. These were 2 diferent type of cars, they may have been put on way to hard, not used a thin skim of oil on the seals.... no idea. But I always thought the Fram filters were good. Just my .02
At the school I teach I spend a lot of time in the shop. We have had 3 FRAM with catastrophic failures in them: you take it off the car and the filter medium has literally disintegrated.
If you consider that we do not do 10 oil changes a day, if anything maybe one a week at best, you can see that it's either that we've had a streak of very negative coincidences with FRAM filters, or they are simply ****.
My 2 cents, anyway.
Back in the mid/late 80's when I was still actively racing motorcycles, Fram filters were illegal- you couldn't roll tech if you had one installed.
WERA had seen a rash of Frams that blew the housings right off the screw base, must have been bad crimps.
I think Fram rectified the problem and were later reapproved but I've never considered using one of their filters again.
