2002 Z28 A4 NBM- Sadly now demodded :(
It depends on the age of the engine, what type of abuse you subject it to and the type of oil.
My 98 at 179,xxx miles is 20-25 psi at idle (M6 ~1000 rpm) using Castrol 10W-40. My 02 at 45,xxx miles is 40-45 psi at idle (A4 ~750 rpm in gear - 750 cuz it's got a 3400 stall) using 5W-30 (IIRC) Castrol Synthetic.
