So it sounds like the answer is oil pressure is oil pressure no matter if it comes from a high volume pump or a standard pump. It seems that a standard pump is set up so that engine wear is taken into account when originally built from the factory. Allowing enough oil/pressure as the engine accumulates miles and/or hours of wear and tear on internal moving parts. I may or maynot use one I'll have to toss a coin on this one. Thanks for the input everyone. Jay
