Seven reasons why car oil lamps shine

Oil lamp alarm may be caused by the following reasons:

1. Insufficient oil quantity of the engine oil reduces the pump oil quantity of the oil pump or the pump does not oil due to air intake, resulting in a drop in oil pressure;

2, the engine temperature is too high, it is easy to thin the oil, from the loss of a large number of gaps with the resulting pressure drop;

3. When the parts of the oil pump are damaged or the clearance is too large due to problems such as wear and assembly, the oil pump will not cause oil or oil shortage.

4. The mismatch between the crankshaft and the large and small tiles is improper. If the tightening is too tight, the oil pressure will increase, and the looseness will reduce the oil pressure.

5, the oil sensor is damaged, the oil filter, suction oil blockage will also reduce the oil pressure;

6. Damage or failure of oil return valve: If the main oil return valve spring fatigue is softened or improperly adjusted, when the mating surface of the valve seat and the steel ball is worn out or gets stuck by the dirt, the oil return amount will increase significantly. The oil pressure of the main gallery will also decrease.

7. If the oil is improperly selected, if the wrong or improper grade is selected, the engine will run at an excessively low viscosity to increase the leakage, thus reducing the oil pressure.
