This is normal. Most cars don't have gauges that indicate the rise and fall of pressure with engine RPM, but all engines do this. You will see higher pressures when the engine is cold. Don't worry about this, everything is OK.

He is correct. The oil pressure is generated using a mechanical pump. The pump is driven off the engine and the pumps speed will follow the speed of the engine. Higher revs of the engine = more oil pressure. My 83 nissan 280zxt has almost no oil pressure at idle and a ton at redline. The engine is at 160K and just getting broken in ;) Don't worry this is completly normal for EVERY 4 stroke engine.
