Ya its normal. Mine sits on 4 bars cold idling and 3 when hot and idling. Cruising at 100 it sits on 5 when cold and then goes to 4 after about 15 minutes. My oil pressure went up slightly when i got them to change the oil at 3000Km on its first service. I brought my own oil 5W40 100% synthetic.
But i see some have higher oil pressures than others, i probably put it down to instrument accuracy.
