It could be a bad gauge sender, bad dash gauge, or stuck pressure relief in the oil pump. Its time to hook up a mechanical oil pressure gauge and verify if the oil pressure is really getting that low.

Re: Low oil pressure? sometimes?

more likely than not your problem is the oil press. sensor . it's located just above the oil filter , easy to change . be careful of brittle plastic on the elect. connector . good luck .

Senders are for gauges, sensors are for computers.
