How many kilometers should a car run before a major maintenance?

Generally, a vehicle needs a major maintenance after running 30,000 kilometers, which includes replacing components such as engine oil and oil filter, air filter, fuel filter, power steering fluid, and spark plugs. Below are the specific details of the maintenance: 1. Lubrication system: The car should be cleaned and maintained every 5,000km-10,000km. 2. Fuel system: The car should be cleaned and maintained every 10,000km-15,000km, or when you notice engine stuttering, sluggishness, poor acceleration, black smoke, lack of power, or increased fuel consumption. 3. Cooling system: The car should be cleaned and maintained once during the seasonal transition between winter and summer, or every 6 to 8 months under normal driving conditions, or when encountering issues like overheating, water leakage, or boiling. 4. Transmission: The car should be cleaned and maintained every 20,000km-25,000km, or when experiencing transmission slippage, high water temperature, delayed shifting, or system leakage.

I drive a Honda Civic, and the manual recommends a major service every 30,000 kilometers, which includes replacing the oil filter, checking brake pads and tire wear. Since I mainly commute in the city with heavy traffic, the engine often operates under high load, so I usually go to the dealership for inspection every 25,000 kilometers to prevent small issues from becoming big problems. Remember, a major service isn't just about changing the oil; you also need to check the transmission system, air conditioning refrigerant, and other details. A friend of mine almost had an accident due to brake failure after skipping a service. My advice is to adjust the schedule based on road conditions: you can wait until 30,000 kilometers if you drive mostly on highways, but do it earlier for muddy roads. Safety first—don't skimp on maintenance costs.

As a car owner, I've tried various vehicles. Japanese cars require major maintenance at 30,000 km, while German cars like Volkswagen recommend it at 15,000 km - quite a significant difference. I often drive long distances, but the mountainous roads are rough, so I perform comprehensive maintenance every 18,000 km, checking the suspension, power steering fluid, and cooling system to prevent sudden breakdowns. Last time I neglected this and drove to 22,000 km, resulting in engine overheating that cost over 10,000 yuan to repair - a painful lesson. It's best to combine the manual with actual driving conditions: frequent city starts accelerate wear, requiring shorter intervals; while highway driving with better fuel efficiency can allow slight extensions. The key is not to rigidly follow fixed schedules.

I've been driving an old sedan for over a decade, and the frequency of major maintenance depends on the vehicle model and usage. For new cars like the Toyota Camry, the manual recommends a major service every 20,000 kilometers, including comprehensive filter replacements and electrical system checks. I'm accustomed to city driving and prefer inspections every 12,000 kilometers to prevent carbon buildup issues. Major maintenance covers much more - it includes battery testing and brake fluid checks, so don't just focus on mileage. Environmental factors matter too: driving in snowy winter conditions requires earlier antifreeze system maintenance. Delaying comes at a high cost - my neighbor's car engine seized and became scrap due to overdue maintenance.
