What maintenance items are required for a car with over 50,000 kilometers?

[VonFelix]

Maintenance items required for a car with 50,000 kilometers: 1. Spark plugs: The replacement cycle depends on the material, generally ranging from 2 to 4 years; 2. Air filter: If it hasn't been replaced for a while, it should be replaced now; 3. Belts and chains: 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, inspection is sufficient without replacement; 4. Engine oil and oil filter: Under high temperature and high pressure conditions in the engine, the shelf life of engine oil is significantly reduced, and its performance declines sharply. Over time, it fails to protect the engine effectively.
