Ok Max, i tried to explain this to you in another thread (
oil pressure drops the longer your
oil circuit is due to the resistance in the system (relief valve opens)),but you would not listen.
I have tested several filters before in regards to differential pressure across the filter and there is VERY little difference between filters (street engines). NO ONE should use a high micron RACE filter on a street engine.
Mobile 1 & K&N are the same filter from Champion labs (both good filters)
Bypass= U guys will never have a issue with this. U change your
oil and filter often so the filter is not that dirty. If it were to bypass (very cold) most of the trash is already held in the filter element.
Some Car manufactures allow up to 15000 miles between oil changes. Most of you change your oil as often as you clean your car
