What are the maintenance items for 50,000 kilometers?

[SanMia]

The maintenance items for 50,000 kilometers are: engine oil and oil filter, four-wheel maintenance, brake inspection, chassis components, and full vehicle fluid and lighting inspection. If a major maintenance has not been performed, additional items such as throttle body cleaning, fuel injector cleaning, air filter replacement, fuel filter replacement, and cabin air filter replacement should be included. Replacing the engine oil and oil filter is a mandatory item for every maintenance service. Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of engine oil is significantly shortened, and its performance degrades substantially, failing to provide adequate protection for the engine. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. If the vehicle's engine uses a timing belt, it should be inspected or replaced at 50,000 kilometers. If the engine uses a timing chain, replacement is not necessary.
