i have a new 05 dually that seems to be running 45 psi on oil pressure and was wondering if thats what it should be.my 02 with lb7 had 80 cold and 60 or 70 warmed up.what should oil pressure be on lly motor

My 05 is 30 psi @idle and 60 when running. 80 when she first starts up. Was told this is normal for LLY.
