Regular items include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. Here are the details: Component lifespan: Some brand manufacturers may add additional maintenance items, which is determined by the lifespan of car components. Some components have a shorter lifespan and are prone to getting dirty, so they need to be replaced frequently. Changing the engine oil: Among these, changing the engine oil and oil filter are essential items. 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 greatly declines. Over time, it fails to protect the engine. The oil filter is replaced simultaneously with the engine oil to prevent impurities from mixing into the oil, causing oxidation and the formation of sludge that can block the oil passages.
Last time when my Golf reached 20,000 kilometers, the mechanic told me these items were mandatory: changing engine oil and filter is the basic service - the engine is like a heart needing fresh blood; the cabin air filter also needs replacement, you only realize how unpleasant those dusty smells are when using AC in summer; the engine air filter affects fuel consumption, I replace it every 20,000 km without fail. They also check brake pad thickness, tire tread patterns and pressure, which directly impact braking distance. After testing the lighting system, the mechanic adjusted the beam angle for safer night driving. Finally comes the complete fluid inspection - coolant and brake fluid conditions must be verified. After completing these services, I felt much more assured.
