I've said it more than once- - - -any oil pressure at all indicates the pump is providing more oil than the engine needs- - - - -AS LONG AS THAT OIL IS GETTING TO THE LAST PLACE IN THE ENGINE THAT NEEDS TO BE PRESSURE LUBRICATED. After that, splash takes over and lubes everything else. Most engines with idiot lights turn the light on at 7 PSI, so no one realizes just how low the pressure can go and still keep all the moving parts slippery. Oil pressure above 30 or so at cruise speed is just wasting energy that could be better used for moving the vehicle down the road.
