What Happens If a Car Runs Out of Engine Oil?

[LeAva]

If a car runs out of engine oil, it can lead to conditions such as engine crankshaft seizure, cylinder scoring, and bearing wear in the engine. Below are the functions of engine oil and how to choose it: Functions of Engine Oil: Engine oil not only lubricates the engine but also helps with cooling, cleaning, and sealing. Without engine oil, all components would operate under dry friction, generating extremely high heat instantly, which could cause these parts to burn out or melt. When the engine is running, numerous metal parts rub against each other, and the longer it runs, the higher the internal temperature becomes. Engine oil is essential for lubrication and cooling during this process. Choosing Engine Oil: When selecting engine oil, pay attention to its viscosity. If the viscosity is too low, the oil cannot form a stable oil film during engine operation, leading to overheating and abnormal wear. If the viscosity is too high, the internal resistance of the engine increases, which may result in sluggish acceleration and difficulty in raising engine RPM when pressing the accelerator.
