ok guys im a little stumped lately ive noticed my oil pressure close to 0 it starts up and hold pressure like it always has when its cold goes up to 60 after a while drops to 30 and itl drive around like that for a while then it randomly drops to almost 0 ive pulled over and stopped for about 5 min and started the car back up again and it and it will hold at 30 for about 10 min then drops again ive checked my oil pressure connector and is is fine could it be the sensor or signs of my pump going out and im running 20w50 oil and the temp here in texas has been hitting close to 100.
