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