What are the major maintenance items for a car at 50,000 kilometers?

[GiannaFitz]

Major maintenance items for a car at 50,000 kilometers: 1. If the car has been properly maintained in daily use and underwent a major maintenance at 30,000 kilometers, then at 50,000 kilometers, you only need to replace the engine oil and oil filter, perform four-wheel maintenance, check the brakes, inspect chassis components, and conduct a full vehicle fluid and lighting inspection; 2. If a major maintenance hasn't been done before, additional items such as cleaning the throttle body and fuel injectors, replacing the air filter, fuel filter, and cabin air filter should be included. Replacing the engine oil and oil filter is a mandatory item for every maintenance session. Due to the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance degrades substantially. Over time, it fails to protect the engine effectively. The oil filter is designed to prevent 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 should be replaced simultaneously.
