What maintenance items should be performed at 20,000 kilometers for a car?

The maintenance items to be performed at 20,000 kilometers for a car include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. The function of the air filter is to block dust and particles inhaled by the engine during the intake process. If the filter is not cleaned for a long time, it will cause the engine to inhale dust, resulting in abnormal wear of the cylinder walls. If it was not replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer maintenance. If the car uses ordinary material spark plugs, then preparations should also be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel the engine's power is insufficient while driving, maintenance should be performed.

I've been driving for ten years, and every time I reach 20,000 kilometers, I have to do maintenance. The main items include changing the engine oil and oil filter, which is the most important—it protects the engine, reduces wear, and prevents overheating failures. The air filter should also be replaced, especially in cities where there's a lot of dust. If not replaced, poor engine airflow can lead to higher fuel consumption. The braking system must be checked to inspect the thickness of the brake pads and the brake fluid level—safety first. Tires need to be checked for wear and proper inflation pressure; if unbalanced, they can cause vibrations at high speeds, so a wheel balance might be needed. Lights, including headlights and taillights, should be tested to ensure they work—driving at night feels safer that way. The cabin air filter is best replaced as well for fresher air inside the car. Other minor items like coolant, battery, and wipers should be inspected, and any issues addressed early. Twenty thousand kilometers isn't too long, but doing these maintenance tasks can extend the car's lifespan. Don't skimp on this—regular maintenance keeps you safe and saves money in the long run.

As a car enthusiast myself, I take notes during every maintenance session. At the 20,000-kilometer mark, the focus is on basic maintenance: an oil change is the core task, and selecting the right oil grade can optimize engine performance. The oil filter should be replaced along with the oil to maintain cleanliness. The air filter also needs replacement, as a dirty one can lead to sluggish acceleration. The braking system should be inspected, including pedal rebound force, and brake pads must be replaced if they exceed wear limits. Tires should be checked for tread depth and pressure to prevent blowouts. Additionally, test both high and low beams during light adjustment. Replacing the cabin air filter improves air quality inside the car, especially for comfortable driving in summer. By not neglecting these fundamental items and performing each one properly, the car runs smoothly and avoids major breakdowns on the road. After such maintenance, the subsequent driving experience feels much smoother.

Safety always comes first, and I pay special attention to safety-related items during the 20,000-kilometer maintenance. The brakes must be thoroughly inspected, checking the thickness of the brake pads and whether there is any brake fluid leakage, as these are critical for survival. Replace severely worn tires to ensure good traction and reduce the risk of skidding. Test the brightness of the lighting system, including headlights and turn signals, as nighttime safety depends on them. Change the engine oil to prevent engine failure, which indirectly affects safety. Clean the air filter to maintain engine stability. Also, check the coolant to prevent overheating and explosions. Other items, such as battery inspection, ensure reliable starting. Prioritize these key points for worry-free driving.
