hello I have a 06 lly and I am wondering were the oil pressure should be at idle when engine is warmed up and where it should be when you are driving and 65 mph with no load on my oil pressure is @ 22psi @ idle and 55psi @ 64-65 MPH is this right? In case you are wondering I am running amsoil 15-40 syn in there oil pressure does not change much when oil has 2 miles on it or 9000 miles on it the only reason I am asking is because i drove a lb7 and the oil pressure at idle was like 35psi warm and 70psi going down the road at 65mph with no load lb7 had about 35k on the clock and my lly has 56k on her now
