Default Re: Oil pressure gauge

The important thing is you took proper precaution and ignored it for 5 hours of driving.

What engine and how many miles are on it? Are you using the correct weight oil? Did the issue appear suddenly or has it been like this for a while?

The sending units are cheap enough that you could start by just replacing that. If the pressure reads normal again you solved the issue. If not time to test the oil pressure with a mechanical guage to see if there is a real problem like a failing pump. I certainly dont recommend driving much more until you fix the issue though, unless your looking for an excuse to replace the engine.
