Do you realize that you just quoted the ideal *GAS* law as an explanation to pressure changes in an *OIL* system?
People will really say just about anything, won't they?

I think both you and EnthuZ(got it right this time) are both right. I believe the gauge measures the pressure that the oil pump exerts to keep the oil flowing at given flow rate.
When the oil is cold, it is denser and thicker, thus requiring the pump to work harder to keep the oil flowing. As the temp rises, the oil becomes less dense and more fluid. The pump has to work less to keep the oil flowing. This shows up as less PSI on the gauge.
PV=nRT is correct, so you might think what gives?
Oil is a fluid not a gas.
Anyway, the Oil Pressure Gauge is just eye candy on a new car. Most people don't know how to use it and it is something that can be monitored electronically by engine management. If you really want to know how to use it, see my earlier post on this thread.

You're right. Nice edit btw.
