Here are the items included in a car's 60,000 km major maintenance: 1. Replace engine oil and oil filter. 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 considerably. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing with the oil, which could cause oxidation, leading to sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. 2. Replace the cabin air filter. The cabin air filter functions similarly to the engine air filter, ensuring clean air when the car's air conditioning is in use. Therefore, it should be replaced regularly. If you notice odors or excessive dust blowing from the vents when using the air conditioning, the cabin air filter should be replaced promptly. 3. Replace brake fluid and brake pads. In the braking system, special attention should be paid to the brake fluid and brake pads. Brake fluid is affected by environmental humidity, and over time, it can lead to reduced braking performance. Similarly, if the brake pads are worn beyond the safe thickness, they should be replaced. 4. Replace spark plugs. The replacement interval for spark plugs depends on their material. Generally, spark plugs should be replaced every 2-4 years. Even if they haven't completely failed, degraded ignition performance can directly impact the car's power and fuel efficiency. 5. Clean the intake manifold and fuel system. By this stage, carbon deposits tend to accumulate in the throttle body, cylinders, and fuel injectors, reducing engine power and, in severe cases, increasing fuel consumption. 6. The maintenance also involves inspecting and servicing dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. Before proceeding with maintenance, carefully review the service checklist and skip any unnecessary items.
