He exaimined bypass valves in FRAM oil filters and was able to make them fail easily
What was the setup of his experiment, details would be nice?

Do you prefer cardboard endcaps, or metal? Maybe cardboard is just as good, but I prefer metal.
Well, if cardboard in this application works just as good as metal (as you say might be the case) then without further data, that becomes a non-issue.

Do you prefer plastic valves, or metal? When you examine the plastic valve, can it be made to fail easily?
What do you mean by "examine?" Under what kind of examination would the valve "fail?" Are they the conditions that the valve would actually see in use?

Do you want for your oil filter to come complete with PTFE in it?
Fram makes filters without it. Yet another non-issue.

FRAM oil filters cut apart (at least the cheaper ones) do not look like fine art.
LOL, that one statement says alot. I'm willing to be I can design a filter that looks beautiful and suck as a filter.

There is an old saying in engineering-if it looks good, it probably is good.
LOL, glad I sliped engineering and went strait to chemistry (that was a joke). I could show you experimental set-ups that look great, but perform poorly.
I'm not saying that these so-called "studies" are crap. For example, there was a site that had bus oil filters that actaully had (I'm not joking) peanut shells and soy sauce packets in it!!!
But, in the long run, the Dremel "studies" only show us what the filter looks like. Since I'm going to be actually using a filter (instead of merely looking at it), I would like to know the filtering characteristics under operating conditions....
And if the cardboard is detrimental to performance, let me see the data.......
Hey, I'm not Fram fanatic...I have a supertech on right now.......it's just unsubstantiated claims (that are personal opinions shrouded as fact) irk me a tad bit.......
So, let's keep on testing and questioning!!!
The truth is out there!!
