Could be a bad oil pressure switch, or a bad oil pump. Both will cause this issue. Hope it is the switch b/c the oil pump is a costly repair.

The idle may be to low or the motor is just old and a new set of rod bearings is need with an oilpump to bring the pressure back up.

There may be a loose wire or the gauge or sending unit may be going bad. The first thing I would do is to hook up a temporary oil pressure gauge, not using the old one at all. With this watch gauge while driving and see what readings you get. If the readings still jump around you have a pump that is getting weak and failing, If that is the case the pump should be replaced, but with high milage you may consider rebuilding the entire engine. If the readings stay normal start checking for a loose wire at gauge or sender. Then check sender, then gauge and replace as needed.
