From what Iíve read and seen, oil pressure on the gauge anywhere between 1-3 bar is fine when you are at idle, but when you are driving (rpm over 1000) you should get 3 bar reading. Not sure if your car has an oil pressure sending unit, but this will be first thing that can cause funny readings. I changed mine once and it fixed my problems. Itís relatively cheap (~$40) and easy to replace. Hope this helps. Good Luck.
