Does exceeding the maintenance mileage have any impact?
2 Answers
If the vehicle maintenance cycle is 5,000 kilometers, generally exceeding it by three to five hundred kilometers for maintenance is not a big issue. However, it is best to follow the requirements for the maintenance of important systems, such as the lubrication system, cooling system, and braking system. Below are the possible impacts of exceeding the maintenance mileage: 1. If the engine oil exceeds the maintenance mileage by too much, the fluidity of the oil deteriorates, increasing engine wear and fuel consumption. In severe cases, it may cause faults such as the engine stalling for no reason, especially for turbocharged engines, the impact is more serious. 2. If the coolant exceeds the maintenance mileage by too much, the engine is more likely to show a high water temperature warning. At the same time, the cooling system is more prone to scale buildup, leading to poor engine cooling performance, which can easily cause the engine to overheat. 3. If the braking system exceeds the maintenance mileage, it can easily lead to brake fluid failure. Prolonged braking can cause the brake fluid temperature to rise and the boiling point to drop. After boiling, the braking system becomes weak and prone to failure.
I've always believed that regular maintenance is extremely important. Last time my car exceeded the recommended service mileage by nearly 2,000 kilometers before I took it in, and the engine was making a terrible buzzing noise. Upon inspection, the engine oil had turned completely black, significantly reducing its lubricating effectiveness, which led to increased wear on internal components and more carbon buildup. The technician explained that degraded oil affects engine performance and increases fuel consumption. Prolonged neglect like this shortens the vehicle's lifespan and leads to costly repairs. Even small components like filters, if not replaced on schedule, can become clogged and affect the cooling system. So never underestimate the risks of exceeding service intervals – timely maintenance saves both hassle and money while preventing breakdown risks on the road.
