I know there are numerous posts about oil pressure, but I have been unable to locate an answer to my question. My oil pressure seemed a little low at cruse (55PSI) on my overhauled O-360 so I added a few washers. While looking over my EFIS engine data after the washers, I noticed my oil pressure (after it is warmed up to 180 degrees) actually increases from 85psi to 89psi when I pull back to idle for landing. Is this normal? Is 85 too high for normal cruse? I get a reading of 100 psi and a high pressure warning at start up when the oil is cold but that usually settles down once the oil hits around 100 degrees. As always I appreciate any input.
