What are the consequences of driving without engine oil?
1 Answers
Driving without engine oil can have the following consequences: in mild cases, it may cause cylinder scoring and damage to the crankshaft and bearings, while severe cases can lead to complete engine failure. Cylinder scoring or engine seizure may occur, and without oil, engine components will experience severe wear, affecting the vehicle's lifespan and the driver's safety. The primary functions of engine oil include lubrication, sealing, heat dissipation, and rust prevention. When oil is insufficient, the engine operates with inadequate lubrication, poor sealing, and insufficient cooling, leading to excessive wear, localized severe damage, or even complete engine failure. If a car idles without oil, it may run for about half an hour. While an engine can start without oil, running it without lubrication will cause irreversible damage.
