Get a mechanical substitute gage on it, if reads too low pull the pan look
for a clogged oil pick up screen, check a few bearings for excess wear ,if
all this is ok, overhaul the oil pump. This job is not for a first timer in
engine repairs. This all assumes an engine with fairly reasonable mileage
and well maintained.
