What maintenance items are required at 30,000 kilometers?

[DelJasmine]

The maintenance items required at 30,000 kilometers are: 1. Engine oil and four filters: The four filters include the engine oil filter, air filter, fuel filter, and cabin air filter. The engine oil filter needs to be replaced every maintenance, while the air filter is recommended to be replaced every 10,000–15,000 kilometers, the fuel filter every 30,000 kilometers, and the cabin air filter every six months. 2. Throttle body cleaning: After prolonged air intake, a lot of carbon deposits accumulate at the throttle body, leading to reduced airflow. This can cause minor idle instability, idle vibration, and weak acceleration, indirectly increasing fuel consumption, so cleaning is necessary. 3. Spark plug replacement: At 30,000 kilometers, spark plugs may not have completely lost their ignition performance, but it has significantly degraded. Reduced ignition performance directly affects idle vibration, engine misfire, and weak acceleration. It also increases engine load, which is one of the reasons for higher fuel consumption. 4. Air conditioning cleaning: Cleaning the air conditioning system removes dust, dirt, and provides a sterilizing effect.
