Disappointed that the Fram Endurance may be going away.
I ran an FE7317 (IIRC; might be a different p/n, but it was for sure an FE) for 3,300+ miles in a V6 Gen 8 Accord, enough to get it into "filter equilibrium," then pulled a sample for analysis, plus a particle count. For particles greater than 14 microns, the Fram endurance posted a very good ISO cleanliness number. It did great with oxidized solids, pulling them out of the oil.
That Fram FE was on par with an NOS Mobil 1 M1-207 filter used in another UOA / particle count trial I did later on (V6 Gen 2 Odyssey). I'd use those filter any day in those Honda V6 applications based on the test results.
Cutting apart a filter and peeking at its insides doesn't give me the information that a UOA and particle count can. Call me skeptical, but I don't think just looking at the media can tell you its efficacy and efficiency at filtering the oil, but I'm just saying that from my own limited perspective. Maybe some people can cut open a filter and do that; I'm just not one of those people with that skill set.
I'm about to get another test done, this time on a sample pulled from my V6 Acura with over a year on the oil fill (Mobil HM EP 0W-20), this one with an AmSOil Ea15K20 filter and almost 10,000 miles on the oil.
