The Aurora is a low pressure oil system. The only solution available at this time is to increase the oil weight. I went o straight 30W to solve the idle alarm issue. Some use 20W oil and that works too.
With 20W you will be at 80 to 90psi cold then drop to 20-30psi hot.
I first replaced the oil pressure gauge and it was worse. I put the original back in and it was better. Then went to 30W and all is fine.
Running it that way for a few years now.

My 1996 olds aurora low oil pressure alarm goes on when my engine speed is below 1000 rpm. I had the oil filter changed and installed Penzoil 20W50 oil in hopes it would control this until I found out what...

100 psi is to much and will blow the seals in the motor.You need to find out what the oil pressure is suppose to be and if it is to low then replace the oil pump.

When my 1996 old aurora get up to temp about 220 the dash warns me my oil pressure is low. AT stops it can drop to 5 to 7 sometimes lower.

see if your oil pressure sending unit is leaking it should be located close to the oil filter. pull the plug off the sending unit to see if oil drips out. if so replace it.

Car is running at 220 deg and at that temp oil pressur drops to 4 psi at idle

have you verified this pressure with a mechanical pressure guage? if not do so, if so u need an oil pump, any engine rattle noises?

98 Olds Aurora V8 gives me an in-dash and audible low oil pressure warning. Engine running normal, there is no tapping and the oil level is where it should be. Oil needs changed according to indicator, but...

check for the oil pressure sending unit. i'm not sure where on the engine this sensor is on your vehicle, but look for a single wire sensor somewhere on the side of the block. hopefully, there'll be a bit of oil dripping from it, because it's a fairly cheap part and easy to replace. otherwise, you may actually have low pressure from a clogged pump pick tube or bad pump.

Oil level system

It may seem obvious but do not operate the engine with it overheating as this can lead to more trouble including a cracked engine block.

Low engine oil pressure is a problem because if it exists, the critical engine parts may not get lubricated properly and may fail. Since you have ruled out external leaks, here are some possibilities:

Clogged oil filter or obstruction in the system

Loose wire or faulty oil pressure or oil level sending switch/sensor.

Possible blown head gasket. This is a serious problem that might be accompanied by white or blue exhaust smoke and a burnt coolant or oil odor. Check for oil contamination with coolant. The dipstick may show a brown milky film/sludge or smell like burnt coolant indicating contamination.

Engine oil pump is possibly bad. This is a serious problem. It's usually time to swap out or rebuild the engine, particularly if it has many miles.

Possible but unlikely in this case is a problem with PCU (Power Control Unit) that runs the Information Center. PCU problems are often indicated by getting other unrelated errors on the info display or "DATE NOT AVAILABLE" for extended periods when you start the car.

You did not mention the Check Engine/Service Engine Soon light being on, but if so I would get the trouble codes read at the OBD II connector. The codes might indicate a sensor problem. Some auto stores do this for free. Either way, I would assume the worse case scenario (bad oil pump) and address it immediately. Unfortunately, due to the complex nature of the car, most things are not easy to diagnose and repair by the do-it-yourselfer. Hopefully though it is just a sensor but with a temperature rise, I would be careful.

Best of Luck!
