Reasons for the Engine Oil Can Light to Illuminate

[MasonAnn]

Below are the related reasons:1. Excessive oil viscosity: The viscosity of the oil is closely related to its quality. The higher the viscosity, the better the oil's resistance to high temperatures, and vice versa. However, higher viscosity is not always better; you should use an oil grade that matches your engine. 2. Pressure relief valve blockage or improper adjustment: To prevent excessive oil pressure in the lubrication system, which can increase engine power consumption and cause oil leaks at sealed connections, a pressure relief valve is installed in the main oil passage or oil pump. Its function is to limit the oil pressure in the lubrication system to not exceed the specified value. A faulty pressure relief valve can lead to abnormal oil pressure, causing the oil light to illuminate. 3. Insufficient oil quantity: If the oil quantity is insufficient, the oil pump's output decreases or fails to pump oil due to air ingress, resulting in reduced oil pressure. This can cause increased wear on the crankshaft and bearings, as well as the cylinder liners and pistons due to poor lubrication.
