At how many kilometers should the first major maintenance be performed for a compact car?

The first major maintenance for a compact car is at 30,000 kilometers. Engine Oil Replacement: Changing the engine oil (mineral oil, semi-synthetic, fully synthetic) is the primary task at 40,000 kilometers. Regular car maintenance (every 7,000-10,000 kilometers) also requires oil changes, and at 40,000 kilometers, it is necessary as well. Engine oils include mineral oil, semi-synthetic oil, and fully synthetic oil, with quality increasing progressively among the three. Transmission Fluid Replacement: Most car maintenance manuals specify that transmission fluid should be replaced every 2 years or 40,000 kilometers. Transmission fluid is typically replaced during "major" maintenance. The transmission is the link between the clutch and the drive shaft, with internal gears being very precise. Frequent gear shifting can cause the transmission fluid to deteriorate, which then fails to provide adequate cooling and lubrication. Coolant Replacement: The replacement interval for car coolant is generally 2 years, aligning well with the 40,000-kilometer major maintenance cycle. Coolants usually come in two colors: pink and blue. The cost of coolant is relatively low, and it is recommended to follow the car's maintenance manual for replacement. Generally, coolant needs to be topped up after driving 40,000 kilometers.

I've been driving since my teens, and cars are like friends that need care. The first major maintenance is usually around 5,000 to 8,000 kilometers, marking the end of the break-in period for a new car. By then, the oil accumulates many impurities, so it's crucial to change the oil and filter promptly. My car had its first maintenance at 5,000 kilometers. The 4S shop conducted a thorough check on the brakes and tires, and even adjusted the tire pressure, making the drive noticeably smoother. Delaying maintenance can harm the engine. A friend of mine postponed his car's service, and the engine started making a buzzing noise, costing over a thousand to repair. Now, I automatically schedule an appointment every 5,000 kilometers to avoid issues. Remember, recommendations may vary by brand—Japanese cars often suggest 5,000 kilometers, while German cars sometimes recommend 7,500 kilometers—but always stick to the manual. Developing this habit has reduced fuel consumption, extended the car's lifespan, and most importantly, made driving much safer.

I enjoy tinkering with my car, and DIY repairs have become a habit. I usually perform the first maintenance at around 5,000 kilometers when the engine is properly broken in. It's essential to clean out the oil sludge, replace the engine oil, and change the air filter. DIY maintenance is quite simple—just buy the right oil and tools, follow online tutorials, and you're good to go. It saves both money and time, and I hate overpaying at 4S shops. Before starting, make sure the engine is completely cool to avoid burns. After the oil change, check the battery voltage and coolant level—don’t slack on the first maintenance. I also inspect the suspension and steering system to ensure a smooth ride. Some people wait until 8,000 kilometers when the oil turns black, only to end up with engine issues. Remember, the first maintenance is crucial—repeat it every 5,000 kilometers afterward, and your car will run smoother. This experience taught me that small investments prevent big losses—maintenance is like adding a shield to your car.

I just got my driver's license and bought a car, so I'm quite concerned about the first maintenance. The 4S dealership recommended doing the first major service at around 5,000 kilometers, so I took it in on time. They replaced the oil filter and air filter, and also cleaned the carbon buildup components. After driving a few hundred kilometers, the car feels quieter and smoother. I recommend new drivers like me to do it early, as delaying it may lead to malfunctions. The car manual clearly states the details, so don't rely on others to remind you. After the maintenance, driving feels much more reassuring, especially on long trips. Regular maintenance is the starting point of caring for your car.
