But maybe we need to think of it in terms of not the failure point, but keeping the engine running perfectly for the entire time you own the car. If finer filtration means the engine stays "as good as new" for a longer period, isn't that worth it? In other words, maybe that engine with 100k on it now doesn't burn any oil, instead of using a quart every 5k if it was slightly worn. Maybe it's making 98% of it's original horsepower instead of being down to 90%. Maybe it still gets the same MPG as new, instead of it dropping by a few %.
A lot of "MAYBE"? It is called the point of diminishing return.
In an engineering design, we usually talk about relative instead of absolute.
Yes, people MAYBE (again) will buy a $20 filter but the segment of population that is educated enough on this topic is probably too small for them to make profit.
While, you can probably see that the Orange Can is selling like hot cake.

3rd: you still need to change the oil and add additives, so why bother. You also have to add oil to deal with burning, etc.
The OEM can make the filter 2x or 3x as big, but they still get changed when it is not filled up, so they shrink it to make it cheaper to make, cheaper to ship, cheaper to stock, and cheaper to dispose.
I agree with this.
