when I crank the car cold, the oil pressure goes up to about 70-75, and after it warms up it will idle at about 25. While driving down the freeway, the pressure stays between 50 and 55, no matter what RPM's I'm at. After driving for a long time, it will idle at about 15-20, when the oil is real warm. Is this normal? For your information I am using 10w30 synthetic oil. if that helps.
