It does NOT automatically mean you have 80# of pressure! NEVER trust your gauges as being the 'last word'. They're notoriously cranky on some older XJ's. (Usually due to gauge cluster connection issues or harness oxidation.)
Chances are that you have a defective oil pressure sending unit. Rarely the gauge goes bad. Remove the wire on the sending unit and see if that changes the reading. If it does, replace the sending unit. If not, I'd still replace the sending unit.
After you confirm the oil pressure sending unit is good, check the oil pressure relief valve. It may be stuck closed resulting in high pressure reading.

What is an oil pressure sensor?
It is an electrical devise that "measures" the oil pressure and converts it into an electrical signal that a computer or the gauge cluster reads.
What if the oil pressure gauge reads high all the time?
It means the filter needs replacement
What does it mean if your oil pressure gauge is high?
If your oil pressure gauge is high you have to much oil in your engine. Overfilling your engine can result in you blowing out your gaskets.
How do you know if oilpump is bad on chevy350?
Need to hook up a oil pressure gauge in the place were the oil sending unit is on the engine and see what the gauge reads, You should have no less then 20 LBS. at a idle. If it does not have oil pressure then pump is bad.
How do you install an oil pressure tach in a 95 Nissan 200sx?
Do you mean an oil pressure gauge? Not tach?
My jeep 2002 jeep oil pressure reads 80?
Probably just a bad calibration on the gauge. I've seen it before, and testing it with another oil pressure gauge shows normal pressures. A: when the oil pressure gauge reads 80 psi it means that there is an open sense circuit. it is most likely a defective oil pressure sending unit, but may also be an open sense circuit wire between the pcm and the oil sender. note: most defective oil senders in this condition are also leaking oil. oil may be seen leaking from the connector seal on the sender.
Oil pressure gauge reads zero after starting the engine then in a couple of minutes goes up a little then jumps to normal and stays there?
Oil pressure has to built up. As long as the pressure is normal and the oil level is good. There is no problem.
What could be wrong if oil pressure gauge reads nothing and the oil pressure light is on in a 1997 Cadillac Catera?
The oil pressure light is on due to the fact that there is no pressure from the oil, fill it up, and if that does not fix it, check for faulty wiring. P.S. There is no such thing as "Blinker Fluid."
Why oxygen gauge reads use no oil?
If you look closely at a regulator gauge you will see the instructions USE NO OIL. There is a reason for this. If pure oxygen or high pressure gas comes in contact with oil it can ignite and cause a fire.
Can you drive 2001 Jeep Cherokee when oil pressure gauge reads 80?
Yes. That is most likely a sensor malfunction and will do no harm. Zero pressure is when you worry.
What is the function of the oil gauge in a car?
The oil gauge shows the oil's temperature. The oil pressure gauge monitors the oil pressure for your viewing pleasure.
How do you install an oil pressure gauge on a zx2?
Connect the wiring harness to the back of your oil pressure gauge. Secure the oil pressure gauge with the retaining screws.
