What are the effects of low engine oil?

[OHailey]

Engine oil deficiency can lead to the following impacts: 1. Poor lubrication in splash lubrication areas inside the engine; 2. When oil pressure drops too low due to insufficient oil, it can cause abnormal operation of the engine's variable timing solenoid valve, leading to inaccurate control of the engine's intake and exhaust valves, resulting in abnormal operation, reduced power, and increased fuel consumption; 3. When oil pressure drops too low due to insufficient oil, it can cause poor lubrication on the engine's friction surfaces, leading to abnormal vibrations, reduced power, and in severe cases, engine bearing seizure. Engine bearing seizure refers to the burning of the crankshaft bearings and bearing bushings due to poor lubrication, manifesting as abnormal engine vibrations until the engine stalls, after which the engine will not be able to restart.
