Weird question, what is the oil pressure gauge supposed to read when the ignition is turned to "on"? What about when its "off"?

The reason I ask is that when I turn the ignition to "on" (not starting the car)it sits a 0. However, when I turn the ignition off, the gauge will give a positive reading.

Is this normal?

When actually driving the vehicle, the oil pressure sits between 40-45 at cruise and sometimes up to 60 @ WOT. No check engine lights.

Hmmm, maybe I found my answer. A guy told me his 2000 Silverado does the same thing. Since its an electronic gauge, it will stick on the last setting prior to shutting the car off (hence it reading 40 with the car off). When the ignition is turned on, it will go to 0 and slowly climb.

Sound about right?

if you dont start the motor, but you put the key to the "on" position, all your gauges are going to be reading like the motor was running. and since the motor is not running you will have 0 oil pressure.
