Does exceeding the mileage without maintenance affect the car?

Exceeding the mileage without maintenance does affect the car. Below is an analysis of the related impacts: 1. Engine oil viscosity decreases: Prolonged use of engine oil will reduce its viscosity, making it watery and containing a large amount of metal debris and gum deposits, severely affecting the lifespan and stable operation of the car's engine. 2. Engine oil sealing performance decreases: This will lead to reduced sealing performance (oil leakage), decreased cooling efficiency (high temperature of engine parts), reduced lubrication (severe wear of engine parts), and diminished cleaning effect (severe gum deposits and carbon buildup inside the engine). 3. Engine oil lubrication effectiveness significantly declines: The lubrication effect of the engine oil will greatly decrease, making the engine prone to carbon buildup, increased noise, accelerated engine wear, and relatively higher fuel consumption.
Last year, I forgot to do the scheduled maintenance on my car on time and delayed it for over 10,000 kilometers, which resulted in a bunch of problems. The engine noise became extremely loud, like an old ox panting, and the power felt significantly weaker. The fuel consumption suddenly skyrocketed to an absurd level—filling up the tank didn’t get me far. Later, when I took it to the repair shop for an inspection, they found the engine oil had turned black with thick sludge buildup. The mechanic said it needed an immediate change, or the engine could even burn out. Delaying maintenance like this not only costs more money but also shortens the car’s lifespan. I’ve learned my lesson now—I set a reminder on my phone to do maintenance every 5,000 kilometers without fail, which saves both hassle and money. For daily driving, regular maintenance is all about preventing problems. Otherwise, minor issues turn into major repairs, and the cost is just too high.
