Since, this is a forum
I would like to state my opinion of "flow" vs. "pressure". My understandings conclude that flow is created by the oil pump which simply flows the oil into the system. The oil pump does not create pressure, restrictions create pressure. Restrictions being width of oil passages, oil clearances, OIL FILTERS, and other passages that oil goes through. This proves exactly what I experience on my vehicle the first time I used an AMS Oil filter, my oil pressure raised approximetly 10-15 psi during normal driving and startup. This would only support your statement that filtering to 1 micron raises the oil pressure because it backs up the flow. (I'm not trying to argue, simply discuss. I always want to learn more. Thanks)
