Mike Wilson proved that Fram makes certain oil filters for Amsoil. So either that proves Fram's quality has improved, or maybe Amsoil's standards aren't what some people would like to believe....
I personally use Donaldsons ELF 7349 filter for the Cummins, and Mann filters on the TDI.
Video is no longer there. What I didn't like about a Fram was they never used a spring loaded by pass, just a plate was used and when the pressure was high it would bend the plate and it now was free flowing. Most people didn't know this. Unless it has now changed I have not seen any thing on this currently.How ever it was shown to this audience when the filters and oil information was given to us through the TDR. I thank them for there effort to educate us.
