  Edit Answer (for another 14 minutes) First thing, don't drive the car until you figure this out. No, don't open the oil pan just yet. First you test the oil sending unit. Could be just a bad sensor or loose wire. This is easy to diagnose. If the sensor tests okay, then you screw a manual oil pressure gauge into the engine and see what the ACTUAL oil pressure is. If it is indeed really below 5 psi (which is what usually triggers a light) then you can open the oil pan and look for a clogged oil screen or a worn out oil pump. (0)(0) Report It

  Edit Answer (for another -2 minute) Does sound like sensor has gone bad, or there is a blockage in the galley leading to it. A manual sensor to monitor the pressure would determine the problem, and give you peace of mind. Could definately be a weak pump, though, so don't drive until you find the problem. (0)(0) Report It

  Edit Answer (for another 0 minute) For what it's worth, opening the oil pan isn't a very big deal, a few screws and a new gasket, so if he's a good mechanic don't hesitate to follow his troubleshooting instincts. Perhaps he has some ideas we don't, and it will show any signs of sludge, unusual wear... etc. (0)(0) Report It
