I have news for you, filter media and filter media surface area does play a huge role in how effective an oil filter is
You completely missed my point. Read it again....if the person that hack-sawed the filter cannister open SAYS that the filters being compared have different TYPES of filter media, then measuring the surface area and using that measurement for comparison means NOTHING.
What if one square inch of media "A" can be tested to determine that it is as efficient and effective as 1.5 square inches of media "B"? Does that not make a simple comparison of the two measurements irrelevant? That sort of simple thinking is abundant on just about all of those comparison sites. Not only that, but many of them start out with a disclaimer like, "I have no background in this field, but...."
The SAE does testing. The oil filter comparison websites do not.
We've all had engines apart that have had excessive wear and damage due to contaminants. There has been NO "smoking gun" so to speak filter-wise in the ones I've seen. It has always been a general lack of maintenance, and/or the conditions the engine is being used in. Have the ones you're talking about had Fram filters exclusively? How do you know that? Have the owners been completely up-front about their maintenance practices? How do you know that?
I'm not a Fram *supporter*, but most of what's been posted about them, (on the 'net especially), is bad science and poor research.
And it can be proven.
