I'm not yet a Boxster owner, but I have many years of both street car and race car experience. Before I would romp on any engine I would like to see about 200 degrees oil temp before hand. If the oil is much cooler than that, it will be relatively thick and not want to flow as it needs to for high RPM operation. It will take several miles past the point of full operating coolant temperature, before the oil temp will be at that level. Since German cars typically bring the coolant temperature up faster than domestic cars, I would want to see maybe 6 or 8 more easily driven miles before pressing very hard on the loud pedal.

Remember, when the oil is cold, the oil pressure will be high. As the oil warms up and thins out, it will have less resistance to flow, thus the oil pressure will decrease. Do some experimenting and see how long it must run before the oil pressure reaches its lowest pressure reading. The oil pressure will peg the gauge with the engine revving up at any temperature, so watch for idle pressure.

My $0.02,
