Having driven over a dozen cars, I feel that the 20,000-kilometer maintenance is particularly important—don’t wait until problems arise to panic. Essential items include changing the engine oil and oil filter, which ensures smooth engine lubrication, better fuel efficiency, and durability. The air filter should also be replaced or cleaned, as it blocks dust to protect the engine—otherwise, power may drop. Check and replace the cabin air filter to ensure no odd smells when using the AC in summer. A thorough inspection of brake pads and brake fluid thickness is crucial—it can save lives in critical moments. Check tire wear and pressure, as shallow treads after 20,000 km increase the risk of skidding. Test the lighting system to ensure clear visibility for night driving. Top up or replace all fluids, including coolant and windshield washer fluid. I usually add a chassis bolt tightening to prevent loosening and strange noises. Remember to do it on time—it’s a small cost to prevent major repairs. It’s best to get it done at a 4S shop or a reliable garage.
