Oil filter Fram or Mann

I use Fram 9/10 times I do an oil change, never had an issue. I have heard more than once that some Fram filters have internal rust from the factory, but I’ve never cut one open to verify this

Fram filters have a lower micron count than other brands, thus why people say they are bad. I would not use them on high performance stuff, but on econoboxes i would. been using exclusively fram on my 2006 corolla since it was brand new and it has 250k miles and still going strong, however on my mustang i only use motorcraft.

I run the ultra synthetic Fram filters , why cus they are made in USA. I’ve had no issues at all, my car has 330k miles bought it with 120k miles

Had an 05 Civic and put 100k miles on it. Used full synthetic + Fram filters every 10k miles. Opened the engine for a timing belt and it was squeaky clean, not even varnished.

I also recently saw one YT channel test Fram and it did really well. It was somewhat restrictive, but it held a lot of dust and did a good job at filtering.

I use the cheapest brand on my daily and no issues after 160k miles ????????

I've used them for 30 years and have nothing to complain about.

I typically go with Mobil 1. Fram has been manufacturing filters that use a little flap of tin for the bypass spring which comes on during high oil pressure situations, and at least in Canada i have seen these fail quite early. And not one or two, but closer to 3/10 i have cut open. I should cut more open as my observations are now a bit dated but in my opinion if it has a actual bypass spring inside of it, they will be more effective in the long run since the ones with a actual bypass spring inside of the filter i have personally never seen one fail yet.

And with filter media, you want it to be the vacuum bag. The canister that simply catches the most crap is not exactly the smallest micron rating, but the filter that returns to normal operation reliably when the vehicle hits operating temperature. And if that filter seems too expensive to run, then you really cannot afford to replace the engine.

Edit: Also it is worth checking out your factory supplied oil filter as they usually spring the bypass correctly for the designed engine oil pressure.

Fram are by far the worst brand I've seen. Fram filters have cardboard caps on the element that can come apart. Some of them don't even crimp the ends of the element to prevent unfiltered oil from going through the gap.

when I took off the FRAM filter there was no oil that came out. After inspecting the filter it seems like it was not filtering out the oil at all. There seemed to be cleaner oil in it instead.

Just stay far far away from FRAM oil filters. I've had nothing but bad luck from those things.
