What are the maintenance items for a car at 100,000 kilometers?

[StLucy]

The maintenance items for a car at 100,000 kilometers include changing the engine oil, oil filter, cabin air filter, and cleaning the engine intake and fuel system. Here are some details about the maintenance items: 1. Engine oil change: Changing the engine oil and oil filter is a must-do for every maintenance service. Due to the harsh conditions of high temperature and high pressure inside the engine, the shelf life of the oil is significantly shortened, and its performance deteriorates over time, eventually failing to protect the engine. The oil filter prevents impurities from mixing into the oil, which can cause oxidation and produce sludge that clogs the fuel system. The engine oil and oil filter should be changed simultaneously. 2. Regular replacement of the cabin air filter: The cabin air filter works similarly to the engine air filter. To ensure fresh air when the car's air conditioning is on, the cabin air filter needs to be replaced regularly. If you notice an unpleasant odor or a large amount of dust blowing out from the vents when using the air conditioning, it's time to replace the cabin air filter.
