Mine started doing that at about 80,000 miles. I checked the oil pressure with a mechanical guage, and it was fine, so I ignored it. Finally, 2 weeks ago when I did the 150,000 mile service, I replaced the oil pressure switch. It cost me about $40 from the local dealer, and took about 10 minutes to change. I can't find the part number right now.

I was just going to suggest checking the actual oil pressure with a mechanical gauge. The dash gauge is reading from a sensor, so there can be wiring problems that affect what it displays. And since someone already suggested checking the oil level, this would be my next step.

If you didn't drain it into a container to measure it, then what it "looked like" could be a wide range. It's best to hook up a $30 mechanical gauge to see what the oil pressure actually is inside the engine. Then you will know if there is a mechanical or an electrical problem (most likely an electrical prob).
