What maintenance is required for a car after driving 20,000 kilometers?
2 Answers
For a car that has driven 20,000 kilometers, the following maintenance items are required: 1. Replace the engine oil and oil filter. Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of engine oil is significantly shortened, and its performance degrades substantially. Over time, it can no longer protect the engine effectively. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. Therefore, both the engine oil and oil filter need to be replaced simultaneously. 2. Replace the air filter. If it was not replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer mark. The air filter's function is to block dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned for a long time, dust can enter the engine, causing abnormal wear on the cylinder walls. 3. If the car uses standard 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, maintenance should be performed. The lifespan of spark plugs varies depending on their material.
My car has just passed 20,000 kilometers, and maintenance at this point is really important. I'll go for a comprehensive check-up. Mainly changing the engine oil and oil filter to protect the engine from cylinder wear and extend its lifespan. Also need to check the cabin air filter, as it tends to accumulate dust at this mileage, affecting cooling performance. Tires and brakes are priorities - inspecting tread depth and brake pad wear, with front tires often wearing faster and needing replacement. Fluid levels like coolant and brake fluid must also be ensured to prevent overheating or brake failure. Since I mostly drive in urban areas, tire and suspension checks are even more critical. These maintenance tasks aren't troublesome and can save big repair costs later. Remember to find a reliable repair shop and have the mechanic test the lights and electronic systems for safety. The whole process takes about an hour to complete, then you can drive with peace of mind.
