What maintenance is required for a new car with over 30,000 kilometers?
2 Answers
For a new car with 30,000 kilometers, the following maintenance is required: 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, the air filter should be replaced every 10,000 to 15,000 kilometers, and the fuel filter is recommended to be replaced every 30,000 kilometers. 2. Throttle body cleaning: Over time, the throttle body accumulates carbon deposits at the throttle valve, leading to reduced airflow. This can cause slight idle instability, idle vibration, and weak acceleration, indirectly increasing fuel consumption. 3. Spark plugs: Although spark plugs at 30,000 kilometers have not completely lost their ignition performance, their efficiency has significantly decreased. Reduced ignition performance directly affects idle vibration, engine misfire, and weak acceleration. The increased engine load due to poor ignition is also a factor in higher fuel consumption. 4. Air conditioning cleaning: Cleaning the air conditioning system removes dust, dirt, and provides a sterilizing effect. This service is optional.
I just drove my new car over 30,000 kilometers and followed the manual for maintenance, mainly changing the engine oil and oil filter to keep the engine running smoothly. The tires need to have their pressure and wear checked, and if they're unbalanced, a four-wheel alignment should be done to ensure safe driving and avoid high-speed skidding. Don’t overlook the brake system—replace the brake pads if they’re too thin, or it could cause issues in emergencies. The air filter might be clogged with dust and should be replaced to save some fuel costs; also, change the cabin air filter to keep the air inside fresh and make breathing more comfortable while driving. Check the levels of various fluids like coolant and brake fluid, and top them up if there’s a leak. Inspect the chassis and suspension for loose bolts, especially on smoother roads. The spark plugs might be worn and should be checked, and for automatic transmission cars, the transmission fluid may need an update. Doing a full check-up can extend the car’s lifespan for years. I recommend going to a reputable shop and not skimping on these small costs, and keeping a detailed maintenance log.
