The main maintenance items for a car include checking and replacing the engine oil, oil filter, fuel filter, air filter, cabin air filter, as well as inspecting and maintaining related systems such as spark plugs, transmission, throttle body, etc. The details of these maintenance items are as follows: 1. Engine oil and oil filter: Inspect and maintain the lubrication system to prevent excessive wear of components caused by deteriorated, insufficient, or contaminated oil. The oil filter should be replaced together with the engine oil. 2. Fuel filter: Maintain the fuel supply system to prevent clogged fuel lines due to excessive impurities, which may result in insufficient engine power or stalling. 3. Air filter: Maintain the intake system to prevent dust and impurities from entering the cylinders, which could cause wear in the compression system. The air filter should be cleaned regularly. 4. Cabin air filter: Inspect the cabin air filter to prevent excessive dust accumulation. If dust enters the evaporator, it may lead to insufficient cooling or malfunction of the air conditioning system. If the dust on the filter is not cleaned for a long time, it may produce odors and pollute the air inside the car. 5. Spark plugs: Maintain the ignition system to prevent excessive carbon buildup on the spark plugs, which could cause misfires, electrode leakage, or failure to spark, making the car unable to start. 6. Transmission: Check the transmission gear oil to prevent severe gear wear or breakage, which may cause abnormal noises, gear jumping, or sticking in the transmission. 7. Throttle body: Since the air filter may not completely remove impurities, the throttle body can easily become dirty. If the throttle plate is dirty, it may cause unstable idling, so it needs to be cleaned thoroughly. 8. Other components such as brake fluid, battery, fuel injectors, and brake pads should also be maintained to keep the car in good condition and prevent malfunctions while driving.
I've been driving for almost 20 years, and the most crucial aspect of car maintenance is regular oil and filter changes. Doing this every 5,000 kilometers can protect the engine's lifespan. The air filter also needs to be checked and replaced; too much dust can affect fuel efficiency. Keep an eye on tire pressure and wear, and rotating the tires ensures even wear and improves safety. Don’t overlook the braking system—if you hear unusual noises, check the brake pads and fluid immediately. The battery usually needs replacement every three to four years, especially in cold weather when it’s prone to losing charge. Coolant is another must—it prevents freezing in winter and overheating in summer. Also, pay attention to small details like lights and belts; timely maintenance saves money and hassle.
As a new car owner, I prefer keeping the maintenance simple. Oil and oil filter changes are the basics, done quarterly to prevent engine carbon buildup. The air filter affects driving smoothness; replace it when dirty to save money. Check tire pressure monthly, and rotate or replace them if worn. Pay attention to brake system sounds, and consider regular professional inspections. Ensure the battery is charged, especially in winter when starting issues are common. Check lights, including headlights and brake lights—replace dim ones promptly to avoid nighttime driving risks.
I enjoy doing simple maintenance myself. Changing the oil is very convenient—just buy the tools and oil, and do it every six months. Removing and cleaning or replacing the air filter improves efficiency. I rotate the tires myself, swapping their positions every 8,000 kilometers. Check the brake fluid's color and level, and top it up promptly if abnormal. Clean the battery terminals to prevent oxidation. Add coolant to the cooling system—don't wait for a leak to fix it. Checking the spark plug gap can save fuel.
