newbold1 Posted April 21, 2008 Report Share Posted April 21, 2008 Just bought a 1996 DeVille for my daughter. It has about 176K miles on it. The oil pressure light keeps coming on at low RPM's... generally at idle when the RPM's are about 650 - 600. If I sit for any length of time I will get a message stating to turn off the engine. However, if I give just a little gas to bring up the RPM's to about 800 or so the light goes out. I had the oil changed right after I bought the car. Currently it has 7.5 quarts of Valvoline Max Life 10w30 oil. Questions: 1. I hear that using 10w40 may fix the problem. I will try that on the next oil change. Anyone able to tell me why that helps? 2. What kind of repair work does the car likely need in order to fix this problem altogether? Any ideas on the cost that will be involved if the likely problem turns out to be the problem? Is this a problem that would typically require major repair work? 3. There are no DTCs being set by this problem. Is that unusual? My DTCs are completely clear. 4. Last question... I am freaking out when that light comes on and especially when the message says to shut off the engine. I am worried to death that I am going to do serious damage to the engine and the fact that it has 176K miles on it makes me that much more nervous about it. Should I be as worried as I am about this problem? Thanks in advance for any insights you may be able to offer! Link to comment Share on other sites More sharing options...
