How many miles can you drive with no oil before engine seizure occurs?

Generally, driving after the engine oil has completely leaked out can lead to engine seizure. Symptoms such as knocking sounds, air leakage noises, abnormal rise in coolant temperature, reduced oil pressure, smoke from the oil filler cap, power loss, oil flooding, or oil traces on spark plugs may indicate engine seizure. Here are some preventive measures: 1. Maintain normal coolant temperature between 70~95 degrees Celsius to prevent engine overheating. Preheating measures should be taken before winter; 2. Ensure proper engine maintenance according to the manual, including correct selection of piston skirt-to-cylinder liner clearance, piston ring end gap, and side clearance. Additionally, control piston misalignment during maintenance and ensure the dimensional accuracy of cylinder liners; 3. Regularly maintain and clean the air filter to prevent dust from entering the cylinders.
Last time I had an oil leak in my car, it almost caused engine seizure. I drove less than 200 meters when the engine temperature skyrocketed and the warning light kept flashing. Engine oil is the lubricant for the engine - when it leaks completely, metal components directly rub against each other, causing heat and expansion, making pistons and cylinders prone to seizing. Once seized, the engine is totaled, and repairs can cost tens of thousands. I was driving at low speed in the city at that time - damage would have been even faster at highway speeds. I immediately pulled over to check and had it towed to the repair shop. Fortunately, I acted in time, otherwise the engine would have been completely destroyed. Checking the oil dipstick before every drive is crucial, especially for older or modified cars which are more prone to leaks. If you discover a leak, don't push your luck - safety comes first.
