Hey Gas,
Just curious, have you modified the oil pressure sending unit or gauge in any way? The reason I ask is because the gauge doesn't actually show your true oil pressure. In stock form there is a pressure sending unit that if it senses over 5psi oil pressure it turns the guage "on". The guage moves up and it has a resistor built into it to keep the needle showing a little more than half way up the normal range. It's basically an idiot light hooked to something that looks like a gauge. I replaced the sending unit with a 0-60psi unit and removed the resistor behind the gauge and now it works correctly. Only costs you about 10 bucks for a sending unit, but you do have to remove the instrument cluster to cut out the resistor.
If you don't want to change it, I would suggest at least removing the sending unit and attaching a normal mechanical oil pressure gauge and check it with that. At normal operating temp and 2000 RPM, you want to see between 40-60psi according to my Haynes manual. At least you'd know if you have a gauge or engine problem.
Hope it helps
CJ
