If the pressure drops too much, an engine can be damaged beyond repair in a matter of minutes.
Why does the oil light come on when I come to a stop?
This sounds like you have a bearing clearance that is excessive enough to cause the oil pressure at low engine rpms (when the oil pump’s output is lowest) to fall below the oil sending unit pressure threshold for when the light turns on. That threshold is often in the 7 psi range. I would try missleman’s suggestion for a new sending unit first.
If the problem persists after that, you will have to test actual operating oil pressure (at idle for instance) as well as the oil pressure switch. Finally, if the oil pressure warning light comes on continuously, unless the warning circuit itself is malfunctioning, that means the oil pressure is too low to operate the engine without damaging it.

What causes oil pressure light to flicker after oil change?
When an engine gets on up into miles, especially extended periods between oil changes, you will develop wear (excessive clearance) at the main & rod bearings. You have oil passages at these bearings to provide lubrication.
Why does oil pressure light come on at idle?
What are the symptoms of a bad oil pressure sensor?
Below are the top 3 symptoms you can expect to see when there is a bad oil pressure sensor in your vehicle. Blinking Oil Pressure Light – If you see the oil pressure light blinking constantly and not staying consistently on or consistently off, then this is an early warning sign that your oil pressure sensor is about to go out.
Why is your oil light blinking?
If the engine oil level is low, this is causing the oil warning light to flicker. This is most likely what is responsible for the occasional flickering of the oil warning light. More specifically, a low oil level will cause the oil pressure inside the engine to temporarily drop.
Why does my oil pressure drop when I come to a stop and?
When I come to a stop the oIl pressure goes down to almost nothing and the red check gauges light comes on. Once I drive off, the check gauges light goes off and the oil pressure goes back to normal. Because the oil pump is engine driven. As the engine speed goes down, the oil pump output pressure decreases.
What is the normal oil psi at idle?
As I have already outlined, when your engine is functioning properly at a temperature it will be in the range of 25 to 40 psi at idle and at 40 to 70 psi at driving speed. Again, these figures will differ slightly with every model of engine so what you really want to look out for is if your oil pressure is lower or higher than the minimum and maxium amount above.
Will low oil pressure cause vehicle not to start?
Low oil levels can cause the engine to seize, or not turn over. An engine seizing because of no oil often results in the engine being taken apart. Not only can low only levels cause a car to not start, but it can also damage the engine.
Will low oil cause over heating?
If you don’t have the correct amount in your engine at all times, it can create stress on the engine. One of the consequences of low oil is, as you probably guessed, overheating . For instance, if your oil is low, it may cause your water pump to work harder than usual.
What oil pressure should I be at, at idle?
The minimum oil pressure at idle is only 5 psi (34.5 kpa). The minimum oil pressure at 2000 engine rpms is 35 psi (241 kpa). Both of these pressures are using a mechanical oil pressure gauge that can measure the low 5 psi readings. Likewise, is it normal for oil pressure to drop at idle? Low oil pressure at idle only, will most often mean that the engine is low on oil.
Why does my oil change light come on?
Your oil change light is on because it is a timer clock, it will remind you to change oil every 365 days or after one year period.
