What are the symptoms indicating insufficient engine oil?

[VonJune]

Symptoms indicating insufficient engine oil include the following: 1. The oil warning light on the dashboard, resembling a teapot with a drop of liquid in front of the spout, will flash continuously. Engine oil is crucial for engine health; insufficient oil can lead to premature wear or even engine failure. The engine may produce unusual noises, and normal driving speed may decrease. 2. The engine may exhibit high water temperature, valve noise, and knocking sounds, with severe cases leading to cylinder scuffing. Insufficient oil can also cause poor lubrication, resulting in component wear and damage to mechanical parts of the engine, such as the crankshaft.
