What is the reason for the oil indicator to stay on?

Hello, here are the reasons why the car oil alarm light is on:

1. The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the pump cannot be oiled due to air intake, resulting in the oil pressure dropping;

2. The engine temperature is too high, which is easy to thin the oil, and a large amount of oil pressure is lost from the mating gap, resulting in a drop in oil pressure;

3. When the oil pump parts are damaged or the gap is too large due to wear and assembly, it will cause the failure of the oil pump not producing oil or insufficient oil output;

4. The matching gap between the crankshaft and the large and small tiles is improper, too tight will increase the oil pressure, and too loose will reduce the oil pressure;

5. The blockage of the oil filter and suction plate will also reduce the oil pressure;

6. Damage or failure of the oil return valve: if the spring fatigue of the oil return valve of the main oil channel is softened or adjusted improperly, and the mating surface of the valve seat and the steel ball is worn or stuck by dirt and closed tightly, the oil return volume will increase significantly, and the oil pressure of the main oil channel will also decrease;

7. Improper selection of engine oil, if the wrong use or improper selection of the brand, the engine will increase the leakage due to the low viscosity of the oil, so as to reduce the oil pressure;

8. There is oil leakage and blockage in the oil pipeline.

1 The oil storage of the engine is too small, resulting in no or little oil in the lubrication system, resulting in low oil pressure. Solution: Add oil to the engine.

2 The oil is too dirty or viscous, resulting in the oil pump not being able to effectively suck in and out the oil, resulting in low or no pressure oil pressure.

Eight reasons why an oil lamp stays on.

Common sense of maintenance Eight reasons why the oil lamp is always on.

Only normal oil pressure can ensure that the oil is delivered to all the friction parts of the engine, too high or too low will affect the normal operation of the engine, and even cause damage to engine parts. Therefore, when the oil lamp alarms, it should be stopped immediately to find the cause, and the work can be continued only after the fault is eliminated.

The following reasons may cause the oil lamp to alarm:

1. The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the pump cannot be oiled due to air intake, resulting in the oil pressure dropping;

2. The engine temperature is too high, which is easy to thin the oil, and a large amount of oil pressure is lost from the mating gap, resulting in a drop in oil pressure;

3. When the oil pump parts are damaged or the gap is too large due to wear and assembly, it will cause the failure of the oil pump not producing oil or insufficient oil output;

4. The matching gap between the crankshaft and the large and small tiles is improper, too tight will increase the oil pressure, and too loose will reduce the oil pressure;

5. The blockage of the oil filter and suction plate will also reduce the oil pressure;

6. Damage or failure of the oil return valve: if the spring fatigue of the oil return valve of the main oil channel is softened or adjusted improperly, and the mating surface of the valve seat and the steel ball is worn or stuck by dirt and closed tightly, the oil return volume will increase significantly, and the oil pressure of the main oil channel will also decrease;

7. Improper selection of engine oil, if the wrong use or improper selection of the brand, the engine will increase the leakage due to the low viscosity of the oil, so as to reduce the oil pressure;

8. There is oil leakage and blockage in the oil pipeline.

The oil light is mainly caused by insufficient oil pressure in the lubrication system, usually due to the following reasons:

The oil pan is not full of oil and check for oil leaks due to poor sealing.

The oil viscosity becomes thinner due to dilution of fuel or excessive engine load and high operating temperatures.

The oil passage is clogged or the oil is too dirty, resulting in poor oil supply to the lubrication system.

The oil pump or oil pressure limiting valve or bypass valve is stuck and working poorly.

The fitting clearance of lubricating parts is too large, such as the crankshaft main bearing journal and bearing, the connecting rod journal and bearing bearing are seriously worn, or the bearing alloy is peeling, resulting in excessive clearance, increasing the oil leakage and reducing the oil pressure of the main oil channel.

The oil pressure sensor is not working well.

There is no correct choice of oil viscosity based on the climate and engine conditions.

The use of oil with too low viscosity increases the oil leakage of lubricated parts, causing the main oil passage pressure to become low. The selection of oil with too high viscosity (especially in winter) will cause difficulty in pumping oil from the oil pump or difficulty in passing through the oil filter, resulting in low oil pressure in the system.

The reason why the oil lamp of the car is on.

1. The viscosity of the engine oil is too large.

The viscosity of the oil is closely related to the quality of the oil, the higher the viscosity, the stronger the resistance of the oil to high temperatures, and vice versa. But it's not that the more viscosity the better, we should use the right oil grade for our engine.

2. The pressure limiting valve is blocked or improperly adjusted.

In order to prevent the oil pressure of the lubricating system from being too high and increasing the power consumption of the engine, resulting in oil leakage at the sealing connection in the oil circuit, a pressure limiting valve is set on the main oil channel or oil pump. Its function is to limit the oil pressure of the lubrication system so that it does not exceed the specified value. A faulty pressure limiting valve can cause the oil pressure to malfunction, causing the oil light to turn on.

3. The amount of engine oil is insufficient.

If the oil quantity is insufficient, the oil volume of the oil pump will be reduced or the oil cannot be pumped due to the air entering the pump, so that the oil pressure will drop, and the crankshaft and bearing, cylinder liner and piston will be aggravated by poor lubrication.

4. The engine temperature is too high.

If the engine cooling system has too much scale, poor heat dissipation, long-term overload operation or too late fuel supply time of the fuel injection pump, etc., the engine will overheat, accelerate the aging, deterioration, and thinning of the oil, leak from the gaps of each mating, reduce the pressure, and turn on the oil fault lamp.

5. The oil bypass valve is faulty.

The oil bypass valve is to maintain the normal oil pressure of the main oil channel, if its pressure regulating spring is softened or adjusted improperly, the mating surface of the valve seat and the steel ball is worn or stuck and closed loosely, the pressure of the oil will be reduced.

6. The oil filter is blocked.

When the oil filter is clogged and cannot flow, the bypass valve located on its base is opened and the oil enters the main oil channel without filtration. If the opening pressure of the bypass valve is set too high or too low, the pressure of the oil pump will rise or fall, which will also cause the alarm light to come on.

Can the oil fault light still turn on?

When the oil pressure is too low or too high, the oil fault light on the dashboard on the car will turn on. Some car owners asked: "Can the oil failure light be turned on"? We will discuss this in three cases.

First, if we see the oil pressure indicator light up after starting, don't turn it on, the first thing is to check the oil dipstick first to see if the oil level is normal, and fill the oil if necessary. If you can't find the problem, go to the nearest repair shop for an inspection.

Second, if you find that the oil warning light is on while driving, you can find a safe place to stop and check, of course, it is limited to the inspection of the engine oil, and you can't make anything to worry about other faults. If you drive normally, you can continue to drive to the nearby 4S shop for maintenance, and pay attention to slow down.

Third, if the oil warning light on the dashboard of the vehicle is on, the car can be driven normally, but there are symptoms such as shaking or acceleration weakness, and continuing to drive is likely to aggravate the wear and tear of the engine, and it can also threaten the safety of your life and property and that of others, so it is better to call a tow truck.

One: insufficient oil quantity (more common).

The oil volume of the oil pump decreases or the pump cannot be oiled due to air intake, resulting in a drop in oil pressure and an oil lamp alarm.

2. The oil pressure switch (oil induction plug) is faulty (more common);

Three: there is a fault in the line between the oil pressure switch and the instrument;

Four: there is a fault in the instrument (the possibility is very small).

Five: insufficient pressure in the internal lubrication system of the engine (more common).

1: The inside of the engine lubrication system is too dirty, and there is gum, which leads to the blockage of the oil channel and the blockage of the filter, so that the system does not establish the pressure normally, 2: The crankshaft bearing, connecting rod bearing, and camshaft bearing wear are too bad, resulting in the lubrication system failing to maintain the lubrication pressure and making the oil lamp light on, 3: The oil pump is blocked or worn too much, and the system fails to establish sufficient oil pressure.

6. The engine temperature is too high.

Although the oil volume is sufficient, the high temperature makes the oil thinner, and a large amount of oil is lost from the mating gap, resulting in a drop in oil pressure.

7. The oil pump is damaged.

When the parts of the oil pump are worn out and the gap between the assembly is too large, and the work is abnormal, the oil pump will not produce oil or the oil output will be insufficient, which will make the oil lamp alarm.

8. Improper selection of engine oil.

The owner is greedy for cheap and chooses the engine oil with a low grade, or the viscosity does not match the original car oil, which will also cause oil leakage, resulting in insufficient oil pressure and alarm.

9. Improper fitting gap between the size and size tiles of the crankshaft.

If the vehicle has undergone an engine overhaul, you should pay attention to whether there is a problem with the engine assembly, too tight assembly will cause the oil pressure to rise, too loose will lead to a decrease in pressure.

10. There is oil leakage and blockage in the oil pipeline.

The oil filter and oil suction plate are blocked, and the oil circuit of the lubrication system is not smooth, which will cause the lubrication pressure to decrease, resulting in the oil lamp being lit, and the oil circuit needs to be checked and cleaned in time. Ten.

1. The oil return valve is damaged or malfunctioning.

If the fatigue of the spring of the main oil return valve is softened or adjusted improperly, and the mating surface between the valve seat and the steel ball is worn or stuck by dirt and closed tightly, the oil return volume will increase significantly, and the oil pressure of the main oil channel will also decrease.

After changing the oil, if the engine is on after starting, it means that the problem is that you need to check the amount of oil, if it is normal, you need to check the oil pump to see if there is a problem, and you need to check the oil pressure sensor to see if there is a problem, if the engine is started. This oil indicator will turn off, which is a normal phenomenon.

Question: I haven't walked 200 kilometers for just three or five days.

The question hasn't changed, but it wasn't like that before.

Answer: I know that in this case, first check the oil to see if the oil quantity is missing, if the oil volume is not missing, then you need to check the oil pump, as well as the oil pressure sensor, and the model of the oil that is replaced, to see if the viscosity is too high, this phenomenon will also occur.

Question: The engine oil is an all-season engine oil.

There is a lag phenomenon when asking questions and walking.

Question, okay, thanks.

The oil indicator light is on for the following reasons:

1. The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the pump cannot be oiled due to air intake, resulting in the oil pressure dropping;

2. The engine temperature is too high, which is easy to thin the oil, and a large amount of oil pressure is lost from the mating gap, resulting in a drop in oil pressure;

3. When the oil pump parts are damaged or the gap is too large due to wear and assembly, it will cause the failure of the oil pump not producing oil or insufficient oil output;

4. There is oil leakage and blockage in the oil pipeline.

The amount of oil is insufficient.

The engine temperature is too high.

The oil pump is damaged.

Improper oil selection.

Improper mating clearance between the crankshaft and the size pads.

For the fault of the oil lamp, it must be repaired in time, and continuing to drive before the cause is found will cause the engine to pull the cylinder and grind the crankshaft.

The reason why the oil indicator light is always on may be caused by the following reasons: 1. The oil volume is insufficient, the oil volume of the oil pump is reduced, or the oil pressure drops due to the inlet air and the pump cannot be oiled; 2. The temperature of the engine pin is too high, which is easy to thin the engine oil, and a large amount of oil pressure is lost from the mating clearance, resulting in a drop in oil pressure; 3. When the oil pump parts are damaged or the gap is too large due to wear and tear, assembly and other problems, it will cause the oil pump to fail to produce oil or insufficient oil, and the indicator light will always be on; 4. If the matching gap between the crankshaft and the large and small tiles is caused by improper liquid conduction, too tight will increase the oil pressure, and too loose will reduce the oil pressure.

There are several reasons why the oil indicator light has been on: 1. The oil volume is insufficient, so that the oil volume of the oil pump is reduced and hail is less, or the oil pressure is reduced due to the intake and the oil pump cannot pump oil; 2. The engine temperature is too high, which is easy to thin the oil, and a large amount of loss from the mating gap leads to a drop in oil pressure; 3. When the parts of the oil pump are damaged or the gap is too large due to wear and assembly, it will cause the oil pump to fail to pump oil or cause oil shortage failure; 4. The matching gap between the crankshaft and the size of the tile is not suitable, too tight will increase the oil pressure, too loose will reduce the oil pressure; 5. The blockage of the oil filter and oil suction plate will also reduce the oil pressure and the oil indicator light will be lit.
