How many kilometers does a sedan need to be serviced?

[MacChase]

Sedans need to be serviced every 5,000 to 10,000 kilometers. Car maintenance refers to the preventive work of regularly checking, cleaning, supplying, lubricating, adjusting, or replacing related parts of the car, also known as car servicing. Car maintenance items include: 1. Replacing engine oil, oil filter, air filter, and fuel filter; 2. Inspecting the body and tires; 3. Checking the braking system; 4. Inspecting the chassis for damage; 5. Checking the fluid levels. The benefits of car maintenance: 1. Ensuring the vehicle's excellent performance condition; 2. Improving driving safety; 3. Reducing engine noise; 4. Extending the vehicle's service life.

I've been driving a sedan for just over two years and found there's no fixed answer for maintenance intervals—it generally ranges from every 5,000 to 10,000 kilometers, depending on the owner's manual recommendations. For instance, my domestic-brand car manual specifies the first service at 3,000 km, followed by oil and filter changes every 7,500 km. With frequent city traffic congestion causing heavier wear, I stick to 5,000-km intervals for garage visits. Highway driving allows slightly longer stretches, but never exceeding 10,000 km to prevent engine carbon buildup or oil burning. Monitor your car's condition—if acceleration feels sluggish or fuel consumption rises, schedule early maintenance. Developing this habit costs little compared to avoiding major engine overhauls, ensuring both peace of mind and safety. Always choose authorized workshops for comprehensive checks including brakes and tires during servicing.

Having worked in the repair industry for so many years, I've seen all kinds of maintenance issues. For ordinary sedans, a maintenance interval of 5,000 to 10,000 kilometers is recommended, but it depends on the model and driving conditions. New or imported cars may start at 5,000 kilometers, while older vehicles require more frequent attention. The type of oil is also crucial: conventional oil should be changed around 6,000 kilometers, whereas synthetic oil can extend the interval to 12,000 or even 15,000 kilometers. Additionally, replacing the air filter and cabin air filter ensures smooth system operation. Delaying maintenance can lead to oil degradation and cumulative engine damage, ultimately resulting in much higher repair costs. I advise owners to follow the manual and not skimp on maintenance—it's like a regular health check-up for your car.

I prefer the concept of green driving, and maintenance is not a one-size-fits-all approach. In congested urban driving conditions, oil changes should be done every 5,000 kilometers to reduce engine burden. For highway or suburban driving with better conditions, high-quality synthetic oil can extend the interval to over 10,000 kilometers, lowering oil change frequency and conserving resources. Pay attention to oil levels and impurities, and conduct regular self-checks to save money and be eco-friendly. Combining daily maintenance like cleaning the radiator can further extend vehicle lifespan and reduce carbon emissions. Choose oil brands wisely to ensure stable performance and environmental benefits.
