i have the same problem on mine.havent measured the oil pressure yet.we should all measure the pressure with a real gauge first.the gauge in the car is no good..it can be alot of different reasons that the gauge in the car shows what it does..and since they all show differently.

at least i will measure mine before i change my oil pump.though im thinkin of a check over my engine in the winther.but yeah.
intresting thread anyways
