Low readings from worn bearings, bad hydraulic lifter, split push rod, oil galley plug backing out. Loose oil pump. Mounting bolts backed out. I've played around with the 4to20ma transducers at work. Some of that works on less then .5 volts.

Rusty,
On an aftermarket engine oil pressure gauge; Is it 100 or 150psi that it needs to be able to read,,,as i know these engines have high op on cold start-up's ?
