Hello there
It all depends what is the temperature of the oil ,what gear are you in?
Ususally when you start the Porsche it should read higher because the oil is thicker.After the engine warms up the reading will go down.
At idle you can see almost no press,which is normal(warm engine).
From the Porsche technical book:
"Oil pressure at90oC oil temperature and speed of 5000 rpm -- bar---approx.5,0"
