If you dont already have one try using an aftermarket numbered oilpressure guage because you might have a bad gauge. You also might try changing you oil because if you relief valve on your oil pump is not working right and your oil filter is clogged this might cause this. Also might try changing out your sending unit to your oil gauge they go out to.
