How long can you drive without engine oil before cylinder scuffing occurs?
1 Answers
If a car idles without engine oil, it can run for about half an hour; if driven without oil on the road, it can last at most 15-20 minutes. Hazards of running without oil: Prolonged operation without engine oil can cause irreversible damage to the engine and even lead to complete engine failure. Causes of cylinder scuffing: Due to the high-speed operation of the car engine, the friction between the pistons and other metal parts inside the engine can reach working temperatures of 400 to 600 degrees Celsius. Without oil lubrication, dry friction occurs between components, and without effective cooling, driving without engine oil for just a few minutes can cause phenomena like bearing seizure and cylinder scuffing due to excessive temperatures. A slightly longer duration can even lead to seized cylinders and complete engine failure.
