I have a 1990 chevy corsica, 3.1L V6, 183,000 miles. My oil pressure has been low lately and after it runs for a while, when I come to a stop light/sign the oil pressure will bottom out. I don't notice any difference in the sound of the engine, it doesn't stall, or idle differently, just bottoms out. I have checked my oil and it is fine, not low or anything. My oil light or check engine light has never come on, is it that it is just getting worn and old? Any Ideas??

Thats a lot of miles on that engine. Have a mechanic check the oil pressure with a manual gauge. That will isolate the gauge circuit. I suspect the engine may be getting tired and loosing pressure internally but to be sure get it checked and go from there. Good luck
