Oil Pressure Too High

It was actually quite simple, I went to a stock flow Melling after I heard they had a bad run of the high flows. Pressure came down to 65 PSI idle, 80 at around 3,000 RPM. I am running 15w-40, am going to change tomorrow to 5w-30, should come down to what I think normal, like 50-PSI idle hot, and maybe 75 PSI max at higher RPM, will let you all know Thanks!
