Oil Pressure Question
We have 1999 Monaco Diplomat with the 5.9 ISB engine and it has 35,000 miles on it, bought it 7 years ago with 24,000 miles and the oil pressure has always read between 20-25 psi on the gauge weather hot or cold, at idle or driving 60 mph (gauge. is 0-80 psi)
I have never really worried about it to much, but was changing the oil and started wondering about it again. Could this be a sending unit problem?
