How Long Can a Car Run Without Engine Oil?
2 Answers
It is not advisable to drive a car without engine oil due to the following reasons: 1. Continuing to drive with insufficient oil can cause the pistons to damage the cylinder block; 2. It can lead to excessive wear and tear on the engine, resulting in its complete failure. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Minimizing gas leakage and preventing contamination from external pollutants; 3. Protecting components from contact with water, air, and harmful acidic gases; 4. Absorbing the pressure rise in the engine cylinder ports; 5. Cleaning dirt generated on the working surfaces of components. To check the engine oil level: 1. Park the vehicle on a level surface; 2. Wait for 10 minutes after stopping the engine, then pull out the dipstick; 3. Hold the dipstick perpendicular to the ground to inspect the oil level.
With over 20 years of driving experience, I know exactly how serious low engine oil can be. If the oil warning light comes on, it means the oil level is too low or there's an issue with the oil pump – continuing to drive poses enormous risks. How much farther can you actually go? Honestly, it's best not to gamble. Even a slight oil deficiency won't last long; typically, serious damage can occur within minutes or just a dozen kilometers. Engine oil lubricates components, reduces friction, and dissipates heat. When oil is low, friction spikes, causing parts to overheat, warp, or even melt. For example, crawling at low speeds in city traffic might buy you 5-10 km, but on highways or uphill climbs, the engine may fail within a minute or two. I've seen many drivers assume they could reach a repair shop, only to seize their engines mid-journey, leading to costly replacements. For safety, pull over and shut off the engine immediately when the oil light activates. Make it a habit to check the dipstick monthly to prevent low oil levels. Never test your luck—by then, regret won't help.
