What happens if you continue driving without engine oil?
2 Answers
Continuing to drive without engine oil will first result in significantly reduced lubrication effectiveness, and in severe cases, it can lead to engine seizure due to lack of lubrication. Below is relevant information about engine seizure: 1. Introduction: Engine seizure refers to a situation where the temperature inside the engine cylinder becomes excessively high, causing the piston to expand and get stuck in the cylinder, rendering the engine unable to function properly. In severe cases, this can even lead to complete engine failure. 2. Causes: There are many reasons that can cause engine seizure, mainly including excessive engine temperature, engine overload operation, and lubrication system failure. Excessive engine temperature: When the engine runs for extended periods or lacks coolant, it can cause the engine temperature to rise excessively, leading to piston expansion inside the cylinder and resulting in seizure.
As a seasoned driver with years of experience, I've witnessed the consequences of people stubbornly driving with depleted engine oil. At first, it might seem fine, but without lubrication inside the engine, metal components like pistons and crankshafts generate excessive heat from friction at high speeds. Soon, the engine temperature skyrockets to hundreds of degrees Celsius, causing parts to melt, deform, and produce harsh noises. This quickly leads to cylinder scoring or crankshaft breakage, leaving the car dead on the road. Repairs at this stage are no minor issue—typically requiring a full engine replacement, costing anywhere from thousands to tens of thousands of yuan. Worse yet, if this happens on the highway, sudden stoppage doubles the risk and can easily trigger a fire. That's why I make it a habit to check the dipstick weekly. Engine oil is cheap to replace—better safe than sorry. Develop good habits and prioritize safety; don't gamble with luck.
