After a car has run over 20,000 kilometers, the main maintenance items include: changing the engine oil, replacing the air filter, replacing the cabin air filter, and replacing the oil filter, among others. Primarily, these involve replacing some wear-prone components and fluids such as power steering fluid, as well as checking the remaining lifespan of other parts. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. It mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, ensure normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.

When the car reaches over 20,000 kilometers, I will conduct a comprehensive maintenance service, focusing on preventing common issues. The engine oil must be replaced with the appropriate grade to ensure optimal engine lubrication. The oil filter should also be replaced simultaneously, as it filters out impurities and extends engine life. The air filter needs replacement as well, as clogging can lead to reduced power output. Check the tire pressure and tread wear, as imbalance can increase fuel consumption or cause vibrations. The braking system requires thorough inspection; if the brake pads are worn beyond the minimum thickness, they must be replaced promptly to avoid dangerously extended braking distances. Additionally, replace the cabin air filter to maintain fresh air inside the vehicle and reduce odors. The battery voltage and terminal conductivity should be checked to prevent starting failures. Adjust the brightness of headlights and taillights to ensure safe nighttime driving. Finally, top up coolant and brake fluid levels, and don’t overlook small details like suspension fasteners. While these tasks may take some time, they help avoid major repairs, save costs, and keep the car running smoothly.

Just past 20,000 kilometers, my maintenance focuses on a few key items. First, change the engine oil and oil filter to keep the engine running smoothly and efficiently. Replace the air filter as well to prevent dust buildup and clogging. Tire inspection is essential—check if the tire pressure is normal, and if there's uneven wear, adjust the balance to reduce road noise. Don't forget to inspect the brake pads and discs to avoid unexpected deceleration failure. Also, replace the cabin air filter to improve air quality. It's recommended to check the spark plugs regularly if the car vibrates, replacing them promptly to eliminate potential issues. Clean the battery terminals to prevent corrosion and ensure smooth starts. These steps are simple and straightforward, and sticking to them will extend the car's lifespan and provide peace of mind while driving.

My experience is to perform all the basic maintenance items after driving 20,000 kilometers. Replace the oil filter set to ensure clean lubrication. Change the air filter to improve breathing efficiency. Check tire wear and adjust tire pressure for balanced safety. Inspect the brake system to prevent failure. Replace the cabin air filter once to eliminate odors. Check the brightness of the lights to ensure safe night driving. These steps can be completed quickly to prevent problems in time, keeping the car running smoothly every day.

For the 20,000-kilometer maintenance, I focus on both safety and economy. Changing the engine oil and filter is essential to reduce wear and save fuel. Tire inspection, including checking tire pressure and tread depth, helps prevent skidding and accident risks. The braking system must be thoroughly inspected, including pads and discs, to ensure reliable braking. Replacing the air filter enhances engine performance and prevents shaking. It is also recommended to replace the cabin air filter to prevent bacterial growth and health impacts. Additionally, checking the battery condition and suspension system stability helps avoid roadside breakdowns. Regular maintenance of these items can significantly reduce repair costs, extend vehicle lifespan, and ensure safer travels.

The car has run over 20,000 kilometers, and I consider long-term cost-saving principles during maintenance. Starting with oil changes, using well-matched lubricants reduces engine wear. Replacing the oil filter removes impurities and saves fuel. Updating the air filter prevents dust intake and extends engine life. Tire inspections for pressure and wear allow early adjustments to avoid blowout risks and reduce hazard costs. Checking the brake system enhances safety and minimizes emergency repair expenses. Replacing the cabin air filter improves comfort and saves on later cleaning costs. I also take time to inspect lights and the battery to ensure reliable starts. These preventive measures are low-cost but maintain the car in excellent condition, avoiding unnecessary expenses and ensuring long-term, stable performance.
