What problems will occur if a car continues to drive without engine oil?

[Thalia]

Driving a car without engine oil will increase the burden on the engine and cause severe damage to it. When a car runs without engine oil, the engine will lack the necessary protection, including lubrication, cooling, carbon deposit cleaning, anti-corrosion, and anti-wear functions. This will lead to increased friction resistance on the surfaces of engine components, accelerating wear and tear, and causing the gaps between parts to continuously widen. Additionally, without oil to immediately cool and dissipate heat, the engine may suffer from burning or cylinder scoring. These conditions accelerate the aging of engine parts and reduce the engine's service life. When the engine oil is insufficient, the lubrication effect on the friction surfaces of internal components will be poor, leading to inadequate lubrication and increased sliding friction wear on the parts. The oil level should be maintained within the upper range of the oil dipstick. Neither a level below the lower limit nor above the upper limit is acceptable. Excessive oil can increase the engine load, affecting performance. Over time, it may damage the engine's exhaust ventilation system, increase carbon deposits, and even lead to oil burning.
