What maintenance is required for a sedan at 50,000 kilometers?

[VonAdaline]

Regular maintenance includes engine oil, oil filter, cabin air filter, engine air filter, etc., mainly depending on the clogging condition of each component. Before this mileage, you might have been using lower-viscosity engine oil, but after 50,000 kilometers, it's better to switch to higher-quality oil. Below are extended maintenance details: 1. Timely oil and filter replacement: Generally, under normal conditions, engine oil should be changed every 5,000 km. If driving in dusty environments, change every 3,000 km. The engine is essentially the heart of a car, containing many metal surfaces that rub against each other at high speeds in poor working conditions with temperatures reaching 400°C to 600°C. Only qualified lubricating oil can reduce engine component wear and extend engine lifespan. 2. Timely brake pad replacement: Vehicle brake pads typically last about 4-5 years or 40,000 km, though this varies based on driving habits, environment, and speed. Cars frequently driven on highways generally experience less wear since brake usage is reduced during high-speed driving, resulting in slower brake pad wear.
