At 6:00 am after driving approx 6 miles to work, the oil pressure gauge reads 1 qt low. At 5:00 pm, driving the same 6 miles home, at the same speed, the oil pressure reads full. What gives?

oil pressure

Model: Carrera, Year:2005, Mileage:9000, Type of use:Street use only
i'm the new proud owner of a very low mileage 2005 carrera. i've noticed that the oil pressure spikes to 5 at start and stays there unless, after warming, the clutch is in or the car is at idle, then it will drop to 2.5 or 3. when accelerating and or running it goes back up to 5. from what i've read i'm guessing this is normal but wanted to make sure. thanks guys. michael
