Actually no. I also like you have used FRAMs for years. It was not due to any brand loyalty per se. I usually bought on price. So for example, I bought a slug of AC Delco oem PF-44 filters for a Z06 Corvette at $2 per filter.
Fram's at the time were 2 for $5. Much as folks will want to convince you otherwise, it is a COMMODITY, and I have bought on price. It is not a real high quality product, but it has sure gotten the job done for me. I have run PH8A filters for years (14 years) and many miles (250,000) on a Toyota Landcruiser with FRAM filters, Mobil One 5w30 oil with 15,000 mile OCI's!!!
Trust me if FRAM (or anyone else for that matter) sells a filter at xxx price, the last thing they want to do is buy a $3k-$50k motor because the innards of the filter exploded in the oil system. Trust me if it were statistically true and relavent I'd be a lawyer and /or hire one and use FRAM exclusively waiting and hoping for one to explode and SUE SUE SUE. This would beat the lottery all to **** !!
So for example, if you buy a 10/15 dollar M1 filter, the best way to ask: is it 5/6 times better than the 2.50 ea FRAM??? More importantly, what does that REALLY mean?
Of late, Champion Labs, known for better quality than say FRAM, sells for cheaper at 2.07 per, masquerading as WM Supertech filters.
The upshot is even on this very specific board, there has been no confirmed and duplicatible statistical studies showing; for example, a FRAM will only let you go 250,000 miles vs a more expensive and "better" filter letting you go say 500,000 miles better. Or however you wish to say it. They do however document that some filters filter better than others. Or that some filters are MADE better.
There have been no real studies comparing the statisitical significance in an engine or engines run side by side, using say synthetic oil comparing a FRAM against the latest and greatest dujour filter!!!!
Normal filter logic goes something like this. Since it is better constructed and filters smaller particles out, yada yada, ^ (therfore) it must be better long term for your engine. While this is very very logical, and to a large degree I EVEN go along with it: it is very short on statistical analysis. Of course, some are indeed more pricey and better made.
The stuff that helps you with "EXTREME" longevity are products like bypass oil filters and preoilers. A very small % of folks even know about them and even smaller % actually USE these products. Even at less than 250. aftermarket prices, it is still not cost effective for the majority of folks; even folks who study a gear head web site like BOBSTHEOILGUY.
