No it is a fail safe. When your oil pressure drops below (on most cars) 30 psi your computer will shut your fuel pump down until you either let it sit for a while and it resets or until oil pressure builds again. Sorry!

Car dies with low oil pressure


You are most likely in a state of partial seizure. I would take that car to a pro quick as your oil pump sounds like its failing and causing the car to lock up and die. Sorry to say but by the sound of it you are going to be in the market for a new motor or a car very soon.

If the oil pressure light ever comes on while you are at speed, the damage has already been done.

Well it could be the sending unit for the gauge.
But odds are the oil pump or engine bearings are worn out.
As the engine warms up, the metal spaces expand and the oil gets thinner. The oil pressure drops some under normal conditions, but not more than 10 or 15psi. Normal idle pressure with the engine warmed up is probably 25psi.
You could check oil pressure with a mechanical gauge to make sure its not the sending unit.
Once the oil pressure starts staying below 20psi for long periods you'll start hearing noises.

Oil pressure gauge drops to zero sometimes when idling. When gas is pressed to move the needle goes back up. It does not do it all the time


Could be the sending unit or an actual problem with the engine.
The oil pressure will be lower at idle than at road speed but should stay above 20psi.

1995 GMC YUKON I HAVE CHANGE THE OIL SENDING UNIT THE OIL GAUGE IS STILL DROPPING TO 20 PSI WHEN EITHER AT A STOP OR IDLING I HOPING THAT THE OIL PUMP NOT GOING I CANT AFFORD TO REBUILD A MOTOR THIS TIME...


you will need to put a pressure gauge right on the engine to see whats real. Do an oil service with filter. This could help, If the pressure is stll low you could put a oil pump in and hope for the best. As long as you have pressure you should be ok. 20psi at idle can be a sign of old oil so cross your fingers.

Oil Pressure Guage


Oil pressure is read by the sending unit, not created by it. If you replaced the sender and do not see a minimum of 20psi there is something wrong inside the engine.Some people will tell you that 5psi is "safe". In reality, in an otherwise perfect engine it may be but in real world application, the 20psi number is the lowest I'd ever accept in any engine.(at idle) Running pressure is influenced by temperature and oil grade, but this should not vary dramatically.
It is best to attach a mechanical oil pressure gauge to the engine and in that way, you can read the exact pressure. If the mechanical gauge reads the same or very close to what you see on the dash, then the reading is correct and if low you will need further diagnosis to determine why.

did you by chance had the oil filter changed because there is a antidrain back valve in the filter,also if the filter is plugging up it will bypass to line pressure.causing lower oil pressure.try the filter first then have oil pressure checked when cold and again when hot.

1992 Dynasty oil pressure drops at stops?


Hi I am Vortash sounds like you have one of four problems either the oil you are using is inferior and you need to upgrade to a better one synthetics are best ..
Your Oils pump is failing reducing the oil pressure ..
Leaky gaskets allowing pressure to ecape .
Or more drasticaly your main bearing shells are wearing giving the the oil more ways to escape under pressure . this is usually discernable by a knocking or rumbling noise especially on tick over .. hope it is just the oil for your sake regards Vortash

If your oil pressure dropped to 0, your engine would seize up within minutes. Most likely the problem is the oil pressure sending unit. A hundred bucks at any reputable shop should be able to take care of it for you.

Oil gauge at start up run about 45psi then drops off 10-20 psi


Thats normal on high milage engines. They do that because the cam and main bearings are warn.
Try an oil treatment.
