Will help any ICE last longer and see the need to explain the why of this system

Is your engine’s oil filter performing to your expectation? Do you even know the performance of your filter? Most people don’t, and if they did, they would be appalled.
Some of the best full-flow engine filters on the market perform at a capture efficiency of 50 percent at a particle size of 10 microns and above. That’s a beta ratio of 2 for those of you keeping score, and these are considered “good” in terms of full-flow engine filtration. In comparison, a beta ratio of 1,000 would be considered “good” in terms of industrial hydraulic filtration. Why is there such a performance difference? The following factors contribute to the variance:
Physical Size
Often limited by physical size, engine oil filters are relatively small when compared to their industrial counterparts. This small size coincides with less filter media surface area through which to pass the lubricant.
Pressure Differential
The pressure differential is the change in pressure from the inlet to the outlet side of the filter. If the pressure differential is too high, a valve will open, allowing the oil to bypass the filter. All engine oil filters or heads are equipped with a bypass valve. This valve is needed so the engine does not become starved of oil as the filter clogs with debris.
