Does exceeding the mileage limit for car maintenance have any impact?
1 Answers
Generally speaking, exceeding the maintenance mileage by 500 or 1,000 kilometers is not a major issue. However, if the car is still under warranty, it's essential to adhere to the maintenance schedule outlined in the manual. Failure to do so may give the 4S dealership grounds to deny free warranty repairs and claims. Below are some relevant details: 1. Engine oil maintenance: The most critical aspect of maintenance is changing the engine oil, which typically falls into three categories: mineral oil, semi-synthetic oil, and fully synthetic oil. Mineral oil usually requires replacement every 5,000 kilometers or 6 months; semi-synthetic oil every 7-8 months or 7,500 kilometers; and fully synthetic oil every 10,000 kilometers or 1 year. Prolonged delays in oil changes can lead to oil degradation, reducing its lubricating properties. This prevents the oil from forming a protective film on engine components, thereby increasing engine wear. 2. Reasons for the initial maintenance period being set at 3 months or 5,000 kilometers: Many vehicles have their first maintenance scheduled at 3 months or 5,000 kilometers (varies by model). This is because new cars go through a break-in period during which engine components interact and rub against each other, leaving fine metal particles in the lubricating fluid. Therefore, by 5,000 kilometers, it's necessary to replace the break-in oil and filter. Additionally, engine oil typically has a shelf life of about 6 months. The oil is added to the car during manufacturing, and by the time the car is sold to the owner and driven for 3 months, the oil is nearing the end of its shelf life, making this the ideal time for replacement.
