Ok I run 20w50 or my oil light comes on and after my engine is warm the buzzer will go off. I have a electronic oil pressure gauge, the gauge is fine. I started my car and it shot up a little past 90 psi, and runs at 90 psi while driving and about 40psi at idle. engine is new, oil pump is new. Reason im asking is because my old engine the oil pressure shot up to 150psi and was blowing oil filter seals. hence the reason i have a new engine. anyone got an idea??
