What are the things that need to be regularly added to a car?

Cars require regular additions such as engine oil, coolant, brake fluid, power steering fluid, and transmission fluid. The regular maintenance items are as follows: 1. Transmission fluid: Whether it's a manual or automatic transmission, both have transmission fluid that needs periodic replacement. Manual transmission fluid is typically replaced every 30,000 kilometers or 2 years, while the replacement cycle for automatic transmission fluid is longer, ranging from 3 years or 60,000 kilometers to 5 years or 100,000 kilometers. The specific replacement cycle should be based on the maintenance manual. 2. Brake fluid: Brake fluid is prone to absorbing moisture, which gradually degrades its performance and affects braking effectiveness. Brake fluid is usually replaced every 20,000 kilometers or 2 years. 3. Power steering fluid: If the vehicle uses hydraulic power steering, the power steering fluid needs to be replaced. Electronic power steering systems do not require fluid replacement. The replacement cycle is generally every 40,000 kilometers or 2 years. 4. Fuel filter: The fuel filter's role is to remove impurities from the fuel. There are built-in and external types. Built-in filters usually have a replacement cycle of over 50,000 kilometers, while external filters are more convenient to replace, typically every 20,000 kilometers.

Having driven for over a decade, I deeply understand the importance of regular car maintenance. For instance, engine oil needs to be changed every 5,000 to 10,000 kilometers. Old oil becomes too viscous, reducing lubrication and causing the engine to hum loudly; in severe cases, it can even lead to engine failure. Coolant is another critical fluid—it prevents freezing in winter and overheating in summer. Regularly check its level and top it up when low. I also frequently refill the windshield washer fluid, which is especially useful during rainy days for clear visibility—just buy a bottle from the supermarket and pour it in yourself. Brake fluid is equally vital, ensuring responsive braking. Leaks or contamination can cause brake failure, posing serious accident risks. Neglecting these small but essential fluids can lead to costly and troublesome repairs as your car starts acting up.
