Here is a detailed introduction to the parts that need to be replaced after a car has run 40,000 kilometers: Engine oil and oil filter: For normal models, they must be replaced every 5,000 kilometers or six months. If full synthetic oil is used, the interval can be extended up to 8,000 kilometers. If the car hasn't reached 5,000 kilometers, the oil and filter should still be replaced at least every six months. Air filter and cabin air filter: The air filter and cabin air filter should be replaced every 20,000 kilometers or two years. In areas with poor climate conditions or heavy dust, this interval should be shortened to one year. Fuel filter, brake fluid, and transmission fluid: A major service is required every 40,000 kilometers, including replacement of the fuel filter and all brake fluid. For automatic transmission models, the transmission fluid should also be replaced. For rear-wheel-drive vehicles, the differential oil needs to be changed as well. Tires: Even if the tire wear isn't severe after 40,000 kilometers, they should still be replaced. Battery: The car battery should be replaced every two years. Generally, a vehicle's mileage over two years is around 40,000 kilometers. Even if the car hasn't reached 40,000 kilometers, the battery's charge level should still be checked.

What Causes Engine Oil Leakage in a Car?

Engine oil leakage in a car occurs when the rubber seals on the engine fail, and replacing the rubber seals with new ones can resolve the issue. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. The main functions of engine oil are to reduce friction and wear on moving parts, clean out sludge (one of the functions of dispersants) and varnish (detergents) in the engine. Engine oil also neutralizes acids produced from fuel and lubricant oxidation (detergents), improves the sealing of piston rings, and cools the engine by carrying away heat from moving parts.
