Plus the data from river_rat's study, and the ISO testing published by Amsoil showed the Toyota filters are very inefficient (51% @ 20 microns ... very bad IMO).
IMO, the end caps on the FRAM orange can are just too thin. I see nothing wrong with a "fiber"/non-metal end cap IF it is thick enough to be stiff enough to not flex and distort with use.
IMO, FRAM could improve the orange can's reputation, and probably reliability, if they made the end caps about twice as thick as they currently are.
Interesting perspective. I'm not pro or anti FRAM, but there are other videos that talk to the amount of testing they do.
You have an opinion, and you're obviously entitled to it, that the end caps are too thin. And I understand your thinking which I believe is that if it flexes too much, it could come apart from the pleats.
But on the other hand, they do seem to do the testing scientifically and have established that it is engineered to meet or exceed OEM standard. There was another video when they went 200 non stop hours with oil at 275f. The oil coked up but the end caps were fine. The nitrile ADBV had gone brittle though. But the point was that it performed within the usage and temperature parameters.
To me this is similar to the engineering that a car manufacturer goes to establishing whether the oci is 3000 miles or 5000 miles. If they say it's 5000 miles based on oil meeting a particular spec, but you use the wrong oil, and you suffer some sort of engine damage, then it's not the oil that was poorly designed. It was your application of it.
If a FRAM is used beyond the mileage or if the pressures or temperatures are outside design parameters of the vehicle, then the FRAM is not at fault.
However, the major difference is that there may be less redundancy in a FRAM orange can than in other filters. So if something does operate outside of expectations, there is more chance of something going wrong with a FRAM.
The filter seems to be a potentially more critical point of failure, so in that case, you are buying extra insurance if you use a filter that is engineered to higher tolerances than a FRAM.
One thing that is interesting to me is that there is something to the idea that fibre bonds to fibre more strongly than fibre to metal. And if the end caps are of a similar strength to the filter material, then these 2 facts together do suggest a robust design.
I have always wondered what strength filter material must have in order to withstand the oil heat and pressure so this would be a point of failure in all filters. Secondly, all filters use glue to seal themselves somewhere. Either to fibre end caps, to metal end caps, or, as in Toyota's case, filter material to filter material. So the glue would seem to be the second point of failure.
So I think evaluations of filter integrity might be well served by looking at many different elements of the filter not just fibre end caps.
Again, I am not pro or anti FRAM. Indeed I don't use them primarily because I like the idea of getting 99.9% efficiency with PureOne in my Ford and go with OEM cartridges on my German cars.
