How Many Kilometers Can Vehicle Maintenance Be Exceeded?
2 Answers
If the vehicle maintenance cycle is 5,000 kilometers, it is generally acceptable to exceed it by three to five hundred kilometers for maintenance. However, maintenance for critical systems should be performed as required (such as the lubrication system, cooling system, braking system, etc.). Effects of exceeding the maintenance mileage: 1. If the engine oil exceeds the maintenance mileage by too much, the oil's fluidity deteriorates, increasing engine wear and fuel consumption. In severe cases, it may cause issues such as unexplained engine stalling, particularly affecting turbocharged engines more severely. 2. If the coolant exceeds the maintenance mileage by too much, the engine is more likely to show high-temperature warnings, and the cooling system is prone to scale buildup, reducing the engine's heat dissipation performance and increasing the risk of engine overheating. 3. If the braking system exceeds the maintenance mileage, it may lead to brake fluid failure. Prolonged braking can cause the brake fluid temperature to rise, lowering its boiling point. Once boiled, the braking system may lose effectiveness and fail.
I'm the type who pays special attention to driving safety. Over the years of driving, I've learned that you absolutely shouldn't exceed the recommended maintenance mileage by too much. The manual usually suggests an oil change every 5,000 kilometers. Going over by 500 or 1,000 kilometers is still acceptable, but beyond that, the risks increase significantly. For example, engine oil deteriorates, thickens, and provides insufficient lubrication, accelerating component wear. You might start hearing strange noises or notice a sudden spike in fuel consumption. On the highway, a sudden brake failure due to neglected maintenance could be extremely dangerous. I especially recommend not exceeding the interval for new cars, as manufacturers may void the warranty if maintenance isn't done according to schedule. Older models can be a bit more lenient, but don't get careless—regularly check oil levels and filter conditions. Overall, exceeding by 10% is the absolute limit. It's best not to delay; safety comes first. Timely maintenance can also extend your car's lifespan and save you money in the long run.
