What are the maintenance items for 40,000 kilometers?
2 Answers
The main maintenance items for 40,000 kilometers are as follows: 1. Changing the engine oil and oil filter is a mandatory item. 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 substantially. Over time, it fails to protect the engine. The oil filter is replaced simultaneously to prevent impurities from mixing into the oil, causing oxidation and the formation of sludge that can block the oil passages. 2. The air filter should be replaced every 10,000 to 15,000 kilometers. 3. If the spark plugs have not been replaced before, they need to be replaced during the 40,000-kilometer maintenance.
Every time I reach this mileage, maintenance becomes a major checkpoint that can't be taken lightly. Start with the basics—changing the engine oil along with a new oil filter. This ensures the engine maintains its power and even saves a bit on fuel costs. The air filter should also be replaced, especially with urban air pollution accumulating over time, which can choke the car and noticeably slow down acceleration. Next up is tire rotation and balancing. After 40,000 kilometers, tires wear unevenly, and rotating them ensures even pressure distribution to prevent unexpected blowouts. Don’t forget to check the brake pads and coolant—I once experienced ineffective braking on the highway, which gave me quite a scare. Thankfully, I had checked them beforehand. For finer details, like replacing the cabin air filter, it ensures fresh air inside the car, making family trips worry-free. Overall, spending a little on maintenance keeps the car running longer and safer. With my years of car ownership, this routine has become second nature.
