Default STI Oil Pressure ?

I have an 02 STI and it is fitted with Defi gauges.
I have never had an oil pressure gauge before so am not sure what readings to expect.
Once the car is pretty hot when driving the gauge reads about 6.5 kg/cm2(is this the same as bar?) but when idling when hot the gauge reads about 2.5,this seems a little low to me,should I be worried or is this normal? Once above 1000 rpm the pressure rises to above 4.

Depends on the viscosity of the oil you are using, but around 85+psi (5.7bar) cruising and 30psi (2bar) at idle are pretty normal.

Your pressure readings are normal. (Kg/cm2 = Bar).

I would only be worried if the oil pressure dropped to 1 Bar or lower. Coming into the pits after 15 or so minutes on track dropped my oil pressure to approx 1.6 Bar for a short while (untill it cooled down a bit).

Quite normal as already posted by Norminski.
Pressure will drop as engine warms to full op. temp. Will be higher with 15/50 Motul than an 05-30 for instance.
