Before making any adjustments to the oil pressure screw, people might test to see whether the oil pressure sensor is working properly. It may not be giving you the actual pressures. My oil pressure was reading very low and I removed the sensor unit and replaced it with a simple fluid pressure gauge (water or oil) and ran the engine. The oil pressure was OK. You may find that the oil pressure is fine and it's the sensor that is faulty.
