Tap on the sending unit with a screwdriver while she's running, if the gauge starts to behave, you've found the bad guy

The sending units are known to go south over time and from oil contamination. LIke wayne said, tap the unit or "wiggle" the oil pressure guage wire to see if there is a loose connection.

Otherwise replace the unit.

Goodday.
