This might be like cursing in "church", but do you think it odd that almost no one has submitted or conducted VOA and UOA's where the only variable is a (blind) filter comparo test!?
Instead, the so called "quality" of construction has been analyzed. While you can imply or make judgements based on real or perceived quality, this really tells you little of the statistical significance of its filtering ability.
So for example, does a Mobil One filter (fine fine filter by the way) at 10 dollars filter 5 times better than a 2 dollar WallyMarty Supertech(ie)? If it does, how is it statistically significant? Does it let you change (in my case) from 15,000 to 75,000 miles between filter changes? Does it make the UOA's cleaner? Etc etc.
Another for example, I ran a 1987 TLC for app 250,000 miles when Fram PH8A filters were like 2 filters for 4-5 dollars or 2-2.5 dollars each. I ran Mobil One 5-10w30 oils. Changed oil every 15,000 miles (or so). Since this was used in business daily use weekend use, different drivers, the local Toyota dealer mechanics did the major maintenance: i.e., adjusted the valves app 16-17 times. They always remarked at how clean the innards were!!!But more importantly innards were hardly worn at all!!!
..."I wanna hear stories from people who've seen engine damage first hand that was directly Fram filter related."...
So trust me, I would be the first to pitch a fit if your quote were true.
So if I am seen as "aiding and abetting heresy "
Not much is said about PREOILERS. They are acknowledge to practically eliminate cold start wear, which is surmized by industry experts and pre oiler marketing folks
to be 50-80% of all engine wear.
