You oil pressure is read by an oil pressure sending unit, that sends information to your gauge. If the sending unit is bad, you can get weird readings. You can either replace it, or have a mechanical gauge hooked up to see the actual pressure.

Testimonial: "Thanks for the information."
SOURCE: Low engine oil pressure on
in order to check the oil pressure, you have to remove the oil sending unit, then screw in the adapter of the oil pressure gage, and then remove the start relay or fuel pump relay from the fuse and relay box, under the hood on the drivers side, and then crank the engine over 3-4 turns, and then record the oil pressure, and then disconnect the oil pressure gage, and then re install the oil sending unit, replace the start relay or fuel pump relay, and then start up the car, and check the oil sending unit , to make sure it is not leaking, if your oil pressure checks out within the specs, then you are fine, if it gives you a low reading, then you could have a bad oil sending unit , or a oil pump going bad on you. i would replace the sending unit first, then see what the gage shows.
