I know the old C-4 Fram filters (cartridge type) that came on my old Ford, appeared to have some cardboard on the ends. At work, I have some ammonia compressors that have Fram cartridge filters and I think they are cardboard too. Why be so afraid of cardboard in the filter, when the media is often made out of filter paper? I have some other ammonia compressors that have Schroeder cartridge filters with metal end caps, and have seen a couple times where the end caps separate from the media when you remove the filter. In the cases where some of the fellows posting here had leaks due to leaving an extra gasket in place - well, that was their own fault (negligence) and not Fram's. If they didn't know the extra gasket was there, that means they never cleaned the mounting surface, and made sure there was no dirt, or anything else on there either. I wonder if they oiled the seal when they installed that original filter, or even tightened it correctly? I remember digging up to 2 or 3 old gaskets out while changing a filter on an older Chev V8 back before they had spin-on filters. That's almost excusable though, because they are pretty hard to detect up in that groove. I'll have to cut some of my old Frams apart to see how bad they look inside. Does anyone else have trouble with rust forming inside new filters stored in an unheated garage? It seems like they could spray some rust prevenative inside to insure against that.

Hey, it's hard to offend someone when they don't know much.That is way I never get offended! I wish I still had the test lab reports on Fram, but I don't.I remember the cardboard showed signs of deteration from hot oil but don't remember how severe.Now that engines are operating at a higher running temperature, I would be more concerned.The filtering media(paper) is made for the specific purpose of fine filtration under extreme operating conditions. It is formed on a sizing drum in a room with very high humidity so the paper doesn't break while being shaped to fit in the end caps. It is applied with an adhesive called plastisol.The adhesion factor is another reason metal end caps are used except for fram's cardboard. At one time Cat, Cummins,Thermoking & Carrier factory service centers were told not to use Fram.My biggest account in Phoenix was the Cat dealer, who used Wix as a secondary & supplemental filter .They could only use OE filters on their own equipment unless it wasn't available through Cat, then it was Wix.Great testimonial.
I am real curious if they are still using cardboard end caps.I know there have been a lot of changes since I left the filter industry & i don't even try to keep up with it!! A question** How can you trade a Tundra for a Toyota Spyder & still be a farmer? We need an "ask Andy" connection, huh!!
Have a good one
