NUMBER TWO: Crappy anti-drainback valve technology. Virtually everyone who has disected and compared oil filters says Fram is in a (bad) league of its own here. Today, when I removed the Fram filter I was expecting the usual amount of oil to come out and, to my surprise, very very little actually did. The filter was therefore virtually empty. This is not good at all, and can definitely lead to premature engine wear.
Fram's crappy anti drainback has nothing to do with the filter not having any oil in it. In fact, it's impossible for the filter to have completely drained. The filters on 5.0s are mounted in a way such that much more than half of the oil couldn't drain out even if there were no drainback valve at all.
Also remember that nothing is stopping the oil from flowing out of the open section. It will also flow back through the filter. The only things that should stay in the filter is the dirt and debris.
I don't use Frams. I don't recommend them. But if you're going to beat something up be truthful about it.
