The oil pressure guage is telling you the pressure inside the lubrication system which is a reflection of the pressure that the oil pump is generating. It is sensed by a sending unit attached to low on the block typically near the oil filter. It is NOT a measurement of the amount of oil in your engine and therefore should never be used to determine if your oil level is low.
Additionally, most original equipment manufacturers (OEM) gauges are nothing more than glorified "idiot lights" that really have no bearing on the actual PSI pressure but are useful mainly to alert you if the needle is showing somewhere radically different than it usually stays at. Be aware that the temperature of the oil will have a bearing on pressure as will the freshness of the oil filter and PCV valve. If the needle shows no pressure it would be a good idea not to drive the car as this may indicate that the oil pump has failed......a very good way to burn up your engine.

How does an oil pressure gauge works?
Most oil pressure gauges operate by a varying voltage. The oil pressure changes the resistance in the oil sensor, causing the gauge to change readings.
What does it mean if your oil pressure gauge is high?
If your oil pressure gauge is high you have to much oil in your engine. Overfilling your engine can result in you blowing out your gaskets.
