Glad to see this thread. I have a NIB Pure One- purolator oil filter left over from my wife’s CRV we traded in. Now I will have a use for it instead of giving it away. Hey, where’s all the forum oil threads ?.... ( Lol).

I had particular analyses called particle counts run on the used oil and on the remaining new from one of the bottles I'd filled the bike with. The used oil had considerably fewer particles of all analyzed sizes (a range of sizes that are the sizes that cause essentially all engine wear) in it than the new had. What that basically means is that the Tough Gard 7317 is a _very_ good filter, and the Ultra is an even better filter than that.
I think the quality (or water content) of gas now days contributes to that longevity.I’d add:
(3) most modern internal combustion engines don’t seem to care much about how clean the oil is - at least for the projected time most folks have them.
Don’t get me wrong, I change oil religiously and use quality parts, but realistically it seems most modern engines will go a long time with minimal maintenance, including oil changes.
There was some thread about a new synthetic that said never change the oil again - just add when low.
I know my ancient Honda mower hasn’t had an oil change in years [emoji15]

I was pleased. (-:
I have been in contact with a (former?) Fram tech person in the past, and my conversations with that person caused me to wonder if it would be this way.
There are a couple of things I've come to accept as fact, based on data I've either generated myself over the years, or come across:
1) New oil is surprisingly 'dirty' from most marketers, and
2) The motorcycle oil filters from everyone I've found do not seem to have any sort of focus on good filtration.
Some Honda scooter engines don’t even have oil filters (three of mine are that way). Honda doesn’t seem too worried about “dirty” new oil or about filtering it. My Honda lawn mower has no oil filter and it’s entering it’s 35th year of successful operation, albeit with regular oil changes.
Honda recommended oil change intervals are lengthening. The NC is now at 16,000 miles and my Honda SUT is somewhere around 18-19,000 miles oil filter change interval.
16,000 mile oil change interval? I know the NC valve check was lengthened to 16,000 but the oil change too?
My mistake. I omitted the word filter, so I’ve since corrected my post. The oil filter change went to 16,000 miles on the schedule for later model years. I don’t know exactly when the schedule changed; perhaps it was 2016. The oil change remains at 8000 mile intervals.
Eons ago Motorcycle Consumer News (MCN) did an oil filter comparison which included cutting the filters with a band saw to have a look inside. I believe the folded material inside the metal can is called "the media" and they found that many of the taller filters had the same height media as the shorter ones, so what appears to be much greater oil filtering capability turns out to be nothing.

I remember that also, along with their oil articles.
Two articles that are at least as scientific as anything ever presented here that led me to use Purolator Pure One filters on my Hondas:
Motorcycle Oil Filters and Air Filters
Engine Oil Filter Study
Fram has been consistently found to be a substandard filter. Has that changed? Perhaps. Not testing on my MCs and autos however.
AND the Pure Ones I have purchased say made in USA.
And now my Popular Mechanics Winter 2018/19 issue has an article from someone that used a Honda engine driven lawn mower for 10 years (no info on hours/usage/abusage) and never changed the oil. Then had it tested and it tested well, still having TBN of 5.0, whatever that means.
Oh so many truths we grew up with might have been "all about the money" just like they are today. Free will - what is that really?
