What happens if the car maintenance mileage is exceeded?
3 Answers
The hazards of exceeding the car maintenance mileage include: 1. If the engine oil exceeds the maintenance mileage, it will lead to poor oil fluidity and changes in viscosity properties. The engine will not be properly lubricated, resulting in increased wear and higher fuel consumption; 2. If the coolant exceeds the mileage, the cooling system's heat dissipation performance will decline. The deteriorated coolant can easily form scale in the system, reducing the engine's heat dissipation performance. Excessive temperature can easily cause the engine compartment to catch fire; 3. If the brake fluid exceeds the maintenance mileage, its boiling point will decrease. Prolonged or frequent braking can cause the brake fluid temperature to rise and boil, producing bubbles that directly lead to weak or failed braking.
I've been driving for decades, and exceeding the maintenance mileage is no small matter. Dirty engine oil can't protect the engine, and parts wear out severely. If the engine suddenly fails one day, it could be a big trouble. Brake fluid may also deteriorate, causing slower response during emergency braking on highways, significantly increasing the risk of accidents. Fuel consumption keeps rising, turning a fuel-efficient car into a gas guzzler, making your wallet even thinner. There's also the warranty issue—manufacturers won't cover it, and you'll have to pay a hefty sum for repairs. Once, my car exceeded the mileage by a thousand kilometers, and the engine started making strange noises—it cost over a thousand bucks to fix. My advice is to develop a habit of checking the fluids and brake system every 5,000 kilometers. Prevention is always better than regret, and safety should always come first.
When repairing cars, I often see vehicles that have exceeded their maintenance intervals coming in. The engine oil has become thin, leading to insufficient lubrication, which causes bearing wear or piston seizure. Brake fluid absorbs moisture, affecting braking performance, and the pedal feels soft when pressed in city traffic jams. A clogged air filter reduces engine power, increases fuel consumption, and pollutes the environment. If not addressed promptly, minor issues can escalate into major faults, making repairs more troublesome and expensive. Pay more attention to your car's condition regularly. Check the filters during oil changes, and don’t wait for the warning lights to come on before taking action. This way, your car will last longer and be more reliable to drive.
