My wife's vehicle, I don't drive it that often, but noticed this winter when first driven that that the oil pressure was at 80psi on the guage. Thought it might have been the oil weight 10w-30, changed the oil this time using 5w-30 synthetic blend. Oil presure when driving still hits around 80psi, until driven a few miles, usually over 20 miles, then seems to come down some. Oil pressure does rise and fall with rpms. Oil pressure has alwats been in the 60 psi range or above. Wife is concerned with it being at 80psi. Have not put a manual guage on it it. Anyone else experience anything like this with their unit. Should I have any major concerns? Engine has about 150000 miles on it and runs strong. If it is the pressure releif assemblt, how much of a pain is it to change and what would your recommendations be.
Thanks in advance,
Bill
