Why is the engine oil light flashing in a car?

[Georgia]

Car engine oil light flashing can be caused by engine oil, pressure relief valve, and other reasons. Oil factors: High oil viscosity and strong high-temperature resistance of the oil can trigger the warning signal. The opposite is also true. However, this does not mean that higher viscosity is always better; you should use an oil grade that matches your engine. Pressure relief valve: Incorrect adjustment or malfunction of the pressure relief valve can lead to abnormal oil pressure, causing the oil light to illuminate. Oil quantity: Reduced oil pumping by the oil pump or failure to pump oil due to air ingress can cause a drop in oil pressure, leading to increased wear on the crankshaft and bearings, as well as the cylinder liners and pistons due to poor lubrication. Engine: Excessive scale in the engine cooling system, poor heat dissipation, prolonged overload operation, or delayed fuel injection timing can all cause the engine to overheat.
