    Oil pressure Fluctuates

    Hi all! I'm a new owner of a 02 WRX. I absolutely love the car and have waited a few years to finally get one. I have a few questions being the noob that I am. When the car is cruising at 1/4 throttle under light load the oil pressure needle rapidly swings +/- 10 psi. If the car is under a load its pretty steady. Also after an extended(25 minutes) time on the highway my oil pressure drops to 20 psi at idle. This seems a bit low but may be normal at higher oil temps caused by 3.5-4k rpms for that period of time. I also notice a slight miss after a highway trip. I have Defi gauges(boost,EGT,Oil Pressure) with are hooked to the Defi Control Box. Thanks for all your help.
