What items are included in a 20,000-kilometer car maintenance?

A 20,000-kilometer maintenance is typically the third service for a car and is generally considered a major maintenance. The routine items for the third car maintenance include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. Some brand manufacturers may add additional maintenance items. More detailed descriptions are as follows: 1. Changing the engine oil and oil filter is a mandatory item. Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of the engine oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine. The oil filter prevents impurities from mixing into the oil, causing oxidation and producing sludge that can clog the oil passages. The engine oil and oil filter are always replaced simultaneously. 2. Secondly, the air filter also needs to be replaced by this time. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced during the 20,000-kilometer maintenance. The air filter's function 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 can lead to dust being sucked into the engine, causing abnormal wear on the cylinder walls. 3. Additionally, if the car uses standard material spark plugs, preparations should be made to replace them at the 20,000-kilometer mark. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel a lack of engine power while driving, maintenance should be performed. The service life of spark plugs varies depending on their material.
The 20,000-kilometer maintenance is quite crucial, and I often handle such projects at auto repair shops. Generally, it involves changing the engine oil and oil filter, as old oil loses its lubricating properties and can damage the engine. The air filter should also be replaced to prevent dust and impurities from clogging the engine. Checking or replacing the spark plugs is essential, as worn-out spark plugs can cause poor ignition and increase fuel consumption. Tire rotation and pressure adjustment are necessary to ensure even wear and prevent blowouts. A brake system inspection is indispensable, as excessive wear on brake discs and pads can affect stopping distance. Finally, checking fluid levels, such as brake fluid and coolant, and topping them up if low is important. The entire process helps the car run smoother and more fuel-efficiently while preventing unexpected breakdowns. It doesn’t cost much but can save on future repair expenses, making it worth doing regularly.
When my car reached 20,000 kilometers, I paid extra attention and focused on a few key maintenance items. Changing the engine oil and oil filter made the engine noticeably quieter. I replaced the air filter to keep the intake tract clear and prevent starting difficulties. The spark plugs were checked as needed—if there were no ignition issues, I skipped replacing them to save money. The tires were rotated and balanced to improve grip, extend tire life, and adjust pressure to prevent bumps. The brake system was inspected to ensure the discs and pads were in good condition for reliable performance when needed. Various fluids, like brake fluid, were checked and topped up to prevent leaks and malfunctions. The whole process was quickly handled at a professional shop, with noticeable results—my car runs longer without any worries.
