The oil pressure should sit at three at start up as she warms up it can go down to .6 bar before you should be concerned the lighter the oil the lower the pressure most of the time (synthetics also tend to lower the pressure but only marginally). At park running and engine warm .6 to three is fine as long as it goes straight to 3 on acceleration. Hope this helps. 5w30 is a light oil i would use 10w 40 as a minimum unless you live in the very cold climates. Do not mean to get an oil discussion going. Personally I like mobil15w50 as it covers my area's temps very well. A oil sensor can give wierd readings so that is a good place to start if you are concerned. My 560 sits at 2 bar in idle warmed up.
