What are the symptoms of a car without engine oil?

The symptoms of a car without engine oil are: 1. The engine temperature becomes excessively hot and the noise increases; 2. Accelerated wear and tear of the engine; 3. Damage to the engine cylinder block, burning of the crankshaft and bearing shells, and in severe cases, the engine may be completely ruined; 4. Engine cylinder scoring or seizure, which affects the lifespan of the vehicle and driving safety. Engine oil plays a role in lubrication, cleaning, sealing, buffering, rust prevention, and heat dissipation within the engine. When the engine is running, the oil forms a thin film on the surfaces of various components inside the engine, preventing direct contact and friction between them. If the oil pressure is too low, the vehicle should be stopped and the engine turned off immediately to avoid irreversible damage. At the same time, contact a 4S shop for roadside assistance and necessary inspection and repairs.
When the engine oil is insufficient, the symptoms in a car are quite noticeable. Having driven for many years, the first symptom I always notice is increased engine noise, like metal knocking or a buzzing sound, due to increased friction between parts. Then, the oil warning light on the dashboard will definitely come on and keep flashing. If you continue driving, the temperature gauge will show overheating, and you might even smell something burning, with the power gradually weakening. In severe cases, the engine may completely stall, with the knocking sound turning into a harsh grinding noise, leading to costly and labor-intensive repairs. I think developing a daily habit of checking is the way to go, like opening the hood every month and using the dipstick to see if the oil level is normal, preventing major issues. Regular oil changes are also crucial, as they can extend the engine's lifespan.
