What maintenance items are included in a 30,000-kilometer major service?
1 Answers
For a 30,000-kilometer vehicle maintenance, the service items include oil change, oil filter replacement, air filter replacement, fuel filter replacement, throttle body cleaning, spark plug replacement, etc. Below is a detailed introduction: 1. Engine oil and four filters: The four filters in engine oil maintenance include: oil filter, air filter, fuel filter, and cabin air filter. We know that the oil filter needs to be replaced every maintenance, while the air filter is recommended to be replaced every 10,000–15,000 kilometers, and the fuel filter is recommended to be replaced every 30,000 kilometers. The cabin air filter is recommended to be replaced every six months. 2. Throttle body cleaning: Throttle body cleaning is not necessary before 30,000 kilometers. After prolonged intake, the throttle body accumulates a lot of carbon deposits at the throttle opening, leading to reduced airflow. The vehicle may exhibit slight idle instability, idle vibration, and poor acceleration, indirectly increasing fuel consumption. At this point, we should inspect components like the throttle body and spark plugs that may cause these issues. 3. Spark plugs: Spark plugs should be replaced at 30,000 kilometers. Although spark plugs at 30,000 kilometers have not completely lost their ignition performance, their ignition capability has significantly degraded. Reduced ignition performance directly affects idle vibration, cylinder misfires, and poor acceleration. The decline in ignition performance increases engine load, which is also a factor affecting fuel consumption. 4. Air conditioning cleaning: Air conditioning cleaning removes dust and dirt from the AC ducts and provides a sterilizing effect. This service is optional.
