Normal... oil pressure will fluctuate between idle and higher RPM.

Default Oil Pres

It will drop at idle and climb during acceleration. This is a normal thing, the oil pump runs off the distribiter shaft. At idle the oil pump is turning at lower rpms and as you increase rpm the pump turns faster, thus low presure at idle and higher presure at driving speed. Just worry when it doesnt do this,
