A car cannot run for very long without oil, as oil is essential to lubricate the engine and prevent its components from rubbing against each other, which can cause excessive wear and tear, overheating, and ultimately, engine failure.
The exact amount of time a car can run without oil will depend on various factors, including the type of car, the age and condition of the engine, and the driving conditions. In general, most cars will begin to experience significant engine damage within 15 to 20 minutes of running without oil.
Therefore, it is crucial to regularly check and maintain the oil levels in your car to prevent damage and prolong its lifespan. If you suspect that your car may be low on oil or experiencing other engine problems, it is best to have it inspected and serviced by a qualified mechanic as soon as possible to avoid costly repairs or replacement of the entire engine.
