How low? Is it above 1 BAR? If so then it is not low. Another cause for low oil pressure is using a Fram oil filter. Fram uses 2 paper elements instead of a paper on the top section & a mat element on the bottom section. The lower mat element is the bypass filter & with an incorrectly manufactured filter, too much oil will pass through the bypass, dropping your oil pressure.

Low oil pressure after it gets up to operating temps? #1 cause is bad main bearings; or perhaps a bad pressure regulating valve on the oil pump output combined with a worn out oil pump combined with the wrong oil viscosity. If he's really lucky, just the wrong oil!
