What are the maintenance items in a car?

[StRyder]

Car maintenance items mainly include the replacement of engine oil and oil filter, air filter, fuel filter, spark plugs, transmission oil, and related system inspection and maintenance items. The replacement of engine oil and oil filter is primarily for the maintenance of the lubrication system. The cleaning and maintenance of the air filter depend on the usage environment, while the fuel filter is generally replaced after driving 20,000 to 25,000 kilometers. Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. Its purpose is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.

I have been driving for over twenty years and have summarized several key maintenance items that cannot be skipped. First, oil changes are the most important—replace the oil and filter every 5,000 kilometers or six months to protect the engine from wear and seizing. Tire checks are also a daily must—ensure proper pressure and even wear to avoid wasting fuel and high risks of blowouts. The braking system is critical—check brake pad thickness and fluid levels to ensure safe and reliable emergency stops. Don’t neglect battery maintenance, especially testing voltage during seasonal changes to prevent unexpected breakdowns. I also regularly inspect lights and wipers to ensure clear visibility and worry-free night driving. Replace coolant and transmission fluid according to the manual’s schedule to extend the car’s lifespan and save on major repair costs. Develop a habit of recording maintenance dates—even a small car can last long with proper care. By doing these regularly, your trips will be safer and more efficient.

My car is used daily to take the kids to school, so I pay close attention to the maintenance items. Oil and filter changes are a must to keep the engine running smoothly and avoid costly repairs. Don't forget the air filter either—replacing it ensures fresh, dust-free air inside the car without any odd smells. Every month, I check the tire pressure and wear to save fuel and prevent unexpected blowouts. For brake maintenance, I always ask the technician to check if the pads are thick enough and if there's sufficient fluid, ensuring reliable stopping power when it matters most. Before summer arrives, I clean the air conditioning system to remove bacteria and mold, preventing health issues. A simple battery voltage test helps avoid cold-weather starting troubles. Regularly verifying the lights and wipers ensures no panic during rainy night drives. These maintenance tasks don't cost much but prevent expensive major breakdowns. Car life is all about attention to detail.

I often do car maintenance myself, finding it both cost-effective and enjoyable. Changing the engine oil is straightforward—just buy quality oil and a filter, but remember to recycle the old oil for environmental protection. Replacing the air filter is as easy as opening the box and swapping it out, much like cooking. I check tire pressure monthly to ensure even wear and save money on tire replacements. For brake pads, I use tools to measure thickness and replace them promptly when they’re thin, avoiding risks. I test the lights with a small device to ensure brightness and safety. Replacing the cabin air filter myself eliminates odors and keeps the air fresh. Following the manual step by step makes it beginner-friendly. DIY maintenance also helps spot potential issues early. The joy lies in controlling the car’s condition, saving money, and having peace of mind.
