As a general rule the oil pressure will drop if the rod and or main bearings are worn excessively. Also could be the oil pump.

Why don't you have oil pressure in a 1997 Buick lesabre?
check the oil pressure snding unit first then check the pressure gage if both are good you need to replace oil pump Oil pumps in buick 3800,s do not go bad. Replace sending unit or the oil pump pickup screen is clogged.
How does the oil pressure gage work?
There are two types of oil pressure guages. The one that has been around the longest, yet is still in use is a mechanical guage. The later developed guage is called an electrical guage, the system for which is comprised of an electro-mechanical sensing unit [commonly refered to as a "sending" unit], and electrical circuit, and an electrically operated guage. On a mechanical gage, oil pressure signal is sent via a small tube to the gage. inside the gage is a hollow curved spring call a Bourdon tube. As pressure increases, it tries to straighten the spring which has a linkage and arm which is connected to a needle which sweeps a calibrated face thus giving you your numbers. On an electric gage system, a voltage source is sent to the gage which passes through a coil which interfaces with a needle arrangement that moves according to the current flowing through the coil. That current is controlled by the sending unit which is screwed into an oil galley in the engine block. There are differant sensing arrangements but the most common is a variable resistor which allows a calibrated amount of current to go to ground, this is calibrated to the gage face and thus you get your numbers.
How do I stop low oil pressure?
You need to find out why you have low oil pressure. Check the oil level first thing. If the oil level is ok, then check the oil pressure sending unit for a leak. You probably should just go ahead and replace it. If the oil pressure sending unit is ok, then have an oil pressure test run on the engine to see for sure if the oil pump is weak and needs replacing. Good advice
1991 acura integra oil pressure light wont go out?
Stop running this engine until you find out why the oil pressure warning light is on. You have low oil pressure. This can be caused by low oil level, defective oil pump, defective oil pressure sending unit, incorrect oil filter. First thing before proceeding is to Change your oil and install a new oil filter, I recommend Purolator.
Why would the check gage light go on in a 1996 grand Cherokee Laredo?
Because the oil is low.
What could it make the oil light go on when the car is at a stop?
Incorrect oil for that vehicle, faulty oil pressure sensor, incorrect idle speed, worn main, connecting rod and cam bearings,
What nicknames does Gage Hubbard go by?
Gage Hubbard goes by Gage Munster.
Why won't the oil stop spilling into the Gulf of Mexico?
It won't stop because it is under a great deal of pressure and the valve on the oil well was destroyed. They are digging two new well to intersect with the existing one to relieve the pressure. lets hope this works. BP is still trying to stop the oil spill ^. but we're trying to stop it with hair. hair easily soaks up oil so if you get ur hair cut, ask if you can donate it for the oil spill. or you can go to 'Matter of Trust' the website and find the oil spil section. hope this helps
Why on a 1998 Neon does the oil pressure light never go off either before starting or after and once the engine is started it stays on but will flutter on and off as the engine revs higher?
Low oil pressure. Causes can be defective oil pump, oil sending unit, or a clogged, defective, or incorrect oil filter. Change the oil and install a new Purolator PL10241 oil filter. If the light is still on, then stop drivng this vehicle and have the oil pressure tested. If it tests out OK, replace the oil pressure sending unit.
Why On a 1993 Cabriolet Collector Edition the Oil Pressure light starts blinking when you slow down or stop but once you hit the gas to go again it stops Changed oil and oil level is fine?
usually this means you have a bad oil pump. low rpms not enough pressure. Check sender first.
Why would a 1987 Chevy truck oil pressure gage go past 60 psi when key turned on and stay there after truck is running replaced sending unit and gages no help?
wire from sending unit may be grounded/shorted out
Why is the oil spill hard to stop?
Because the leak is thousands of miles under the ocean so the pressure would kill somebody if they even tried to go there. The pressure would crush even a submarine
