The guys on here who are really good at engines will be able to give you a better answer, but I am old school and like lots of oil pressure. I grew up stretching the relief springs in oil pumps so they would put out 80 pounds, so that is my education. Today, I understand the current thinking is that too much oil pressure isn't necessarily desirable........something about it blowing the oil past the bearings too fast. At least that is what we were told relative to marine engines when I was in that business. They told us 25-35 is absolutely fine at higher rpms, these days.

But I still get nervous when mine dips below 45 pounds. We'll see what some others say, who know more than me.
