Fram C3P depth filter 2 microns filtration

I called Fram and they told me it filters down to 2 microns.. This is not a spin on filter, It is an element that is installed in a can. Then the lid is bolted on top. Apparently a depth filter is different than a full flow filter. I had just installed a bypass filter on my car and was wondering about my boat. The 2 IH 392's in the boat have only a bypass filter using the C3P. Anyway I was happy to find out that the C3P is fine. One reason I posted was so if others wonder about a C3P they will know it is a good filter. And I will remember now as well.

I did not install an AMSOIL filter but this gives you an idea of how they work.

Fram is a recognized leader and innovator in the field of filtration with a reputation earner over generations.

That being said somewhere along it is alleged that Fram chose, with malice of forethought, to maximize profits by reducing the materials and manufacturing costs of their filter products by lowering quality.

The 'Oil Filter Study" report has been all around the web for almost a decade now and if the information contained within that report was false or materially misleading I would have expected the Fram Company (now owned by Honeywell) to have taken editorial or legal action to refute the mis-information.

Nor can I recall any authoritative publication issuing any defense or rebuttal.

Even the commercial automotive magazines who derive a portion of their income from Fram have not come to the defense as far as I am aware.

I've seen a Fram filter opened up, and I can vouch that filter element inside does, indeed, have cardboard end caps. After decades of using nothing else, I now use only the Purolater+ or Wix filters.
