Quote: I had used Fram for some time then read several filter "teardown" posts and links with pics. There's not much filter area in the Fram and filter material and valving seems cheap. Those posts along with credible reports of bypass valves sticking open or closed steered me away. No I have never blow up an engine or lost oil pressure with one... I don't plan to find out by trying either. I use something else.
Sounds like a smart and prudent conclusion to me!
As far as you guys trying to build a better mousetrap, google fuel polishing systems for boats (particularly passagemakers with diesel engines). There is no reason to "re-invent the wheel", this has all been well thought out before.
