How Often Should a Car Undergo Major Maintenance?
2 Answers
It is recommended to perform a major maintenance service for your car every 20,000-30,000 kilometers or every 2 years. Below are the maintenance item intervals: 1. Engine oil and oil filter replacement primarily focuses on lubricating system maintenance. Under normal circumstances, this should be done every 5,000 kilometers. 2. The air filter's function is to filter air before it enters the cylinders, removing impurities such as dust, sand, and other foreign particles. It generally needs replacement every 20,000-25,000 kilometers. 3. Spark plugs are consumable parts that require replacement every 20,000 kilometers. 4. Proper installation of the fuel filter can prevent cylinder wear caused by impurities and moisture mixed into gasoline during storage, transportation, and refueling. To ensure optimal engine performance, the fuel filter replacement cycle is typically every 20,000 kilometers or annually.
My family car has been running for almost ten years, and I pay close attention to the frequency of major maintenance. Generally, I take it for a comprehensive check-up every two years or 30,000 kilometers. Since I drive daily for commuting and taking the kids to school, the engine and brake system are prone to wear and tear. A friend at the 4S shop recommended changing the engine oil and oil filter every time, as well as checking the brake fluid and coolant levels. If you often drive in dusty areas, the air filter should be replaced earlier. I remember once delaying maintenance for half a year, and a minor issue turned into a major repair costing over a thousand dollars. So, regular inspections not only save money but also avoid the embarrassment of breaking down halfway, giving much more peace of mind. During maintenance, don’t forget to have the mechanic check the tire pressure and tread depth—cars driven frequently on highways wear out faster, and safety should always come first. Once you develop the habit, the car runs smoother, and you don’t have to worry about sudden breakdowns affecting daily life.
