How often a car should be serviced depends on the vehicle's condition and the grade of engine oil used. If the car is in good condition and uses a higher-grade engine oil, servicing every 10,000 kilometers is acceptable. Car considerations: Reasonably determine the maintenance interval: Scientifically determining the mileage intervals for various maintenance tasks not only keeps the car in good technical condition but also saves on maintenance and repair costs. Generally, a new car in good technical condition, used under favorable conditions, can have its maintenance cycle appropriately extended. Conversely, a car in poor technical condition or used under harsh conditions should have its maintenance cycle shortened accordingly. Understand the total maintenance costs: To prevent the vehicle from entering the repair phase prematurely, it's best to understand the total maintenance costs as much as possible. Utilizing various advanced maintenance equipment and methods for non-disassembly maintenance can not only avoid unnecessary damage to the car's assemblies and components caused by disassembly but also significantly speed up the maintenance process, thereby reducing the total maintenance costs. Proper use of oil: Proper use of oil includes two aspects: fuel and lubricating oil. Improper fuel selection can easily lead to issues such as clogged fuel filters, causing the engine to idle unstably, accelerate poorly, and increase fuel consumption. It can also accelerate cylinder wear and affect the engine's lifespan.

Regarding the issue of every 10,000 kilometers, I personally believe it shouldn't be a one-size-fits-all approach. It depends on what car you drive, what kind of engine oil you use, and your driving habits. For example, my old German car's manual states that with full synthetic oil, maintenance can be done every 15,000 kilometers. However, since I often encounter traffic jams in the city, with the engine running at low RPM for extended periods, I prefer to change the oil at 8,000 kilometers. On the other hand, my colleague's new Japanese car's manual clearly requires maintenance every 5,000 kilometers. Additionally, the driving environment should be considered. If you drive in areas with heavy sand and dust, the air filter might get too dirty by 7,000 kilometers. Therefore, I suggest checking your car's user manual for the most reliable information, as the maintenance intervals specified are based on engineers' tests for specific models. Always pay attention to changes in the engine sound, and if something feels off, don't push the mileage limit.

From my personal experience, a 10,000-kilometer interval is feasible under certain conditions. My car currently follows this schedule, but only with the best full synthetic oil and mostly highway driving. However, there are key points to note: The air filter can't last 10,000 km - I replace it myself around 7,000-8,000 km given fluctuating air quality. Tire rotation can wait until 10,000 km, but brake pad inspection should align with maintenance. Most crucially, establish routine checks - inspect the dipstick every two weeks and top up if below minimum. Oil filter quality matters too; I once used a cheap one that started leaking at just 7,000 km. So don't focus solely on mileage - oil quality and daily maintenance are more important.

I think car depends on the specific condition of the vehicle. For new cars, follow the manual for the first two years, and you can appropriately extend intervals after the warranty expires. Take my American SUV as an example - the dealership recommended maintenance every 5,000 km, but after switching to full synthetic oil, I changed it to every 7,000 km. Actually, the most crucial engine maintenance is cleaning combustion chamber carbon deposits. For vehicles driven mostly in urban areas, I suggest adding fuel system cleaner every 5,000 km. Tire pressure monitoring must be checked during every maintenance - uneven tire wear can be dangerous if not detected promptly. Car batteries typically last about two years - don't wait until it fails to replace it. Ultimately, 10,000 km intervals are too long for certain components - like cabin air filters which I replace every three months myself. It's best to keep a maintenance log documenting everything done each time.

When it comes to intervals, I believe the most important factor is the condition of the engine oil. Last year, I tried using conventional mineral oil in my car, and after driving 8,000 kilometers, I noticed a lack of power during acceleration. Upon inspection, the oil had become as thick as soy sauce. Switching to full synthetic oil did allow it to last up to 10,000 kilometers, provided there were no extreme conditions. For example, driving long distances continuously for ten hours in the summer can cause the oil's performance to degrade quickly. Cars in northern regions with frequent cold starts during winter should also have their maintenance done earlier, as low temperatures can cause oil emulsification, which is harmful to the engine. The moisture content in brake fluid should also be checked; if it exceeds 3%, it needs to be replaced. I recommend paying for an oil test at around 7,000 to 8,000 kilometers—it only costs a few dozen yuan and can tell you whether you need to perform maintenance ahead of schedule. Honestly, the most hassle-free approach is to follow the car's built-in maintenance reminder, as most new cars now come with this feature.

From my experience, the cycle should be comprehensively considered: brand recommendations, oil type, and driving conditions all need to be taken into account. For example, I've driven German cars that require maintenance every 15,000 kilometers, while Japanese cars require it every 5,000 kilometers. Now, with my domestic SUV, the manual suggests maintenance every 10,000 kilometers, but the 4S shop always wants me to come in every 5,000 kilometers. A compromise is to do maintenance every 7,500 kilometers using semi-synthetic oil, which offers the best cost-performance ratio. The key is to learn how to monitor the oil life monitoring system; when it shows 10% remaining, it's time for a change. Don't follow the oil change cycle for transmission fluid—that only needs to be changed every 60,000 kilometers. Here's a little trick: record the fuel consumption after each maintenance; a sudden increase in fuel consumption is a signal for maintenance. If you're really unsure, spend a hundred bucks on an exhaust gas analysis—it can directly assess the engine's health.
