Oil shortages are quite common, and the main reasons for oil shortages include:

1.Oil temperature too high, poor oil separation

2.Oil surge leading to oil deficiency

3.The oil level regulating valve is not turning smoothly, causing abnormal oil quantity.

4.The filter is too dirty, preventing normal oil return.
