Every car owner must know that only under the normal oil pressure can the oil be transmitted to all the friction parts of the engine in time. If the pressure is too high or too low, it will affect the normal work of the engine. In the past, it will cause damage to the engine parts, which will lead to the artificial reduction of the life of the vehicle. So as a car owner, when the engine oil lamp gives an alarm, he should stop immediately to find out the cause, and then he can continue to drive after troubleshooting. This not only protects the car, but also makes our driving safer.

The following is an analysis of the eight causes of the oil lamp alarm, so that you can eliminate this hidden danger in the first time:

 

 

1. The temperature of the automobile engine is too high: when the engine of the vehicle is at high temperature, it is very easy to dilute the oil. After thinning, a large amount of oil is lost from the fit clearance, resulting in the decrease of oil pressure, which causes the oil lamp alarm.

 

 

2. Too little oil: some car owners don’t pay attention to it for a long time after filling the engine oil once, which leads to the decrease of the oil in the oil pump. The insufficient oil in the oil pump will cause the oil pressure to drop, which leads to the oil lamp alarm.

 

 

3. Clearance between crankshaft and large and small bearing: another reason for oil lamp alarm is that when the clearance between crankshaft and large and small bearing is too tight, the oil pressure will increase, otherwise, if it is too loose, the oil pressure will decrease.

4. Oil pump damage: when the oil pump parts are damaged or the clearance is too large due to wear, equipment and other problems, the oil pump will not be able to produce oil or the oil is insufficient. This is the fourth reason for the oil lamp alarm.

 

 

5. The filter and oil suction pan are blocked: the fifth reason for the oil lamp alarm is that the oil filter and oil suction pan are easily blocked by impurities if they are not cleaned for a long time, resulting in the decrease of oil pressure.

6. Choose inappropriate engine oil: some car owners are greedy for cheap engine oil, borrow other people’s or buy inferior engine oil. In fact, this is not worth the loss. If you use the wrong oil or choose the wrong brand of oil, it will increase the leakage when the engine is running due to the low viscosity of the oil, which will reduce the oil pressure and cause the oil lamp to alarm.

7. The oil return valve is damaged or out of order: if the spring of the oil return valve in the main oil passage is fatigued, softened or improperly adjusted, and the fitting surface between the valve seat and the steel ball is worn or jammed by dirt, the oil return volume will increase obviously, and the oil pressure in the main oil passage will also decrease, followed by the oil lamp alarm.

8. Oil pipeline problem: the last reason for the oil lamp alarm is that when the oil pipeline is not replaced for a long time, resulting in oil leakage, blockage and other phenomena, the oil can not be delivered to the engine smoothly.

As a qualified car owner, taking care of your car is to ensure the safety of yourself and your family. Ping An starts from every little thing. Let’s seriously deal with every little detail of your car from now on.
