What Maintenance Should Be Done at 20,000 Kilometers?

For a vehicle that has traveled 20,000 kilometers, the following maintenance should be performed: 1. Replace the engine oil and oil filter. This is a mandatory item for every maintenance service. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance deteriorates considerably. Over time, it can no longer protect the engine effectively. The oil filter is designed to filter out impurities, providing protection for the engine. Therefore, both the engine oil and oil filter should be replaced simultaneously. 2. Inspect the air filter. The air filter reduces the intake of air containing impurity particles, thereby minimizing the risk of wear and damage. During the 20,000-kilometer maintenance, check if the air filter is dirty. If it is excessively dirty, replace it; if not, simply clean it with an air gun. 3. Check the spark plugs. In a gasoline engine's ignition system, spark plugs introduce high-voltage current into the cylinders to generate sparks, igniting the combustible air-fuel mixture. If you notice a lack of power, it may be time to replace the spark plugs. The lifespan of spark plugs varies depending on the material: iridium spark plugs should be replaced every 80,000–100,000 kilometers, platinum spark plugs every 50,000–60,000 kilometers, and nickel spark plugs every 20,000–30,000 kilometers. 4. Inspect the brake pads. During the 20,000-kilometer maintenance, check the thickness of the brake pads. If they are excessively worn, it is advisable to replace them to ensure driving safety.

My own car has just passed 20,000 kilometers, and based on experience, basic maintenance is essential at this point. Changing the engine oil is a must—over time, the engine accumulates dirt, and fresh oil provides lubrication to prevent wear. Don’t forget to replace the oil filter as well, or the oil can get dirty quickly. Check the brake pads and brake fluid; excessive wear can affect braking distance, and safety comes first. Rotate the tires to even out tread wear, prevent uneven wear, and improve fuel efficiency. Make sure the coolant level is sufficient, as high summer temperatures can lead to overheating. Also, replace the cabin air filter to prevent odors and maintain air quality. All these services should cost around 300-400 RMB, ensuring peace of mind and extending your car’s lifespan.

As a long-distance driver, I need to perform thorough maintenance at the 20,000-kilometer mark. Changing the engine oil and oil filter ensures powerful engine performance. The spark plugs should also be inspected, as worn-out plugs increase fuel consumption—replacing them can boost efficiency. A comprehensive check of the braking system, including brake discs and fluid levels, ensures responsive braking. Tire balancing and rotation are crucial to prevent uneven wear and reduce the risk of blowouts. The coolant and battery should also be inspected to avoid breakdowns on the road. Additionally, cleaning the throttle body improves air intake. Proper maintenance at this stage ensures smooth and reliable driving, significantly enhancing the overall experience.

After driving for several years and reaching 20,000 kilometers, I prioritize simple and efficient maintenance items. Changing the engine oil is crucial, paired with a new oil filter. Check the brake pad thickness and replace them promptly if too thin. Rotating tires saves costs, while maintaining even tire pressure prevents abnormal noises. Top up the coolant for better engine cooling. Replace the cabin air filter to keep the air fresh inside the car. These basic maintenance tasks don't cost much and can be done in just over ten minutes, giving me peace of mind when driving to work or picking up the kids.

As a new car owner, I just went through the 20,000-kilometer maintenance, following the manual step by step. Changed the engine oil to prevent aging, and replaced the oil filter to avoid clogging. Checked the brake fluid and pads to ensure safe braking. Rotated the tires to balance wear and extend their lifespan. Topped up the coolant if low to prevent overheating. Replaced the cabin air filter to prevent musty odors. These preventive maintenance steps cost little but help avoid major issues, keeping the car running smoothly and saving money in the long run.
