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

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.
I've been driving for almost twenty years and I know all too well the catastrophic consequences of continuing to drive without engine oil. Engine oil acts as the lubricant for the engine, reducing friction between components, dissipating heat, and cleaning carbon deposits. Once the oil is depleted, the high-speed rotating parts inside the engine will grind against each other dry, generating extreme heat. At best, this causes increased wear, leading to louder noise and reduced power; at worst, it can seize the pistons or damage the bearings within minutes, leaving the car stranded. This not only ruins the entire engine but can also incur repair costs exceeding tens of thousands, and may even cause accidents on highways. I’ve encountered cases where drivers ignored the oil warning light, resulting in complete engine lock-up and costly towing and overhauls. For safety, it’s crucial to develop the habit of checking oil levels every 5,000 kilometers.
Buddy, I'm telling you, don't risk driving without engine oil! The purpose of oil is to lubricate engine parts. Without it, friction between parts generates heat extremely fast. My old car once had all its oil leak out, making loud noises and smoking, nearly destroying the entire engine. It stalled on the road after less than 10 kilometers. The mechanic said the bearings had melted and needed replacement. Not only did it cost money, but it also delayed my trip. Now, I always carry a dipstick and check regularly, especially before long trips. Remember, if the dashboard warning light comes on, pull over immediately to check—don't wait until it's too late.
