Last time when my car reached 30,000 kilometers, I took it to the service station for a check-up and replaced quite a few things. Engine oil and oil filter are must-haves, as the smooth operation of the engine depends on them. The air filter also needed replacement—with so much dust on the road, it can affect performance if it gets clogged. Spark plugs typically need to be replaced at 30,000 kilometers for better ignition efficiency; my friend’s car once wouldn’t start because of old spark plugs. The brake pads were checked for wear—safety comes first. The cabin air filter was also recommended for replacement, making the air much fresher when using the AC in summer. Tire rotation or checking tire pressure is crucial too, saving fuel and preventing blowouts. Actually, for every service, referring to the owner’s manual is key—some parts may not need replacement but just cleaning. I’ve done this kind of maintenance multiple times, and now my car has run 80,000 kilometers without major issues. Regular minor maintenance saves you from major repairs.

When it comes to 30,000-kilometer car maintenance, I prioritize changing the engine oil and oil filter—it's as fundamental as eating. The air filter shouldn't be overlooked either, as dust buildup can restrict airflow. Replacing spark plugs at this mileage improves acceleration response. Always check the braking system, especially brake pad thickness; I constantly remind myself that safety details can't be neglected. Replacing the cabin air filter is recommended too for better interior comfort. Rotate and balance tires to even out wear and extend lifespan. Take the opportunity to inspect coolant and battery condition to prevent unexpected issues. While modern cars have electronic reminders, manual attention remains more reliable. Regular maintenance keeps your car energetic—my experience shows this small investment prevents future headaches and proves trustworthy.

At 30,000 kilometers, the car requires the following maintenance replacements. Engine oil and filter must be changed to ensure good engine lubrication and durability. Replace the air filter if it's dirty, as it affects engine health. Check the spark plugs and replace them if worn out to ensure timely ignition. Inspect the brake pads and replace them if too thin to ensure safety. Also, address the cabin air filter to keep the air fresh and reduce odors. Rotate the tires to ensure even wear and extend their lifespan. Adjust these steps according to the manual; not all may need replacement, but inspection is essential. I drive carefully, maintaining my car on schedule to prevent major repairs. Safe driving relies on detailed maintenance, which is worth emphasizing.

How Long Can a Private Car Be Left Undriven Without Issues?

Private cars can be left undriven for up to one month. It is recommended to drive the car at least once a month for no less than half an hour each time. Prolonged inactivity can lead to battery discharge. Hazards of long-term parking: Tire aging: The contact points between the tires and the ground are prone to aging. The contact points between the tires and the ground may deteriorate, and even the wheel rims could develop subtle deformations, making the car feel unstable when driven. Frame deformation: Parking on uneven surfaces can cause severe issues, such as doors becoming difficult to open or failing to seal properly. This can also lead to an unstable chassis, increased noise, and suspension oil leaks during driving. Precautions for vehicle parking: Even when the car is locked, the battery still experiences a small current drain, leading to power loss. It is advisable to disconnect the negative terminal of the battery if the car will be parked for 15 days or longer. Always choose flat surfaces for parking, preferably in areas monitored by cameras, and avoid parking near garbage piles or tall grass.

What is the fuel tank capacity of the BYD Surui in liters?

The fuel tank capacity of the BYD Surui is 50 liters, which is the officially announced data. Owners who have purchased the BYD Surui can also check this information on the vehicle's configuration sheet. The BYD Surui uses 92-octane fuel, with a fuel consumption of 5.9-6.5L per 100 kilometers. A full tank of fuel can cover a distance of 769-847 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. This is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. Generally, when the fuel gauge shows 2 segments remaining, it is time to refuel to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safety level, and there is still some space from the safety level to the tank opening. This space is reserved to allow for fuel expansion when the temperature rises, preventing overflow from the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

Why does the car display 'service' and fail to start?

This is the vehicle's anti-theft indicator light, indicating that the engine has entered an anti-theft state. Below is an introduction to the car's anti-theft system: 1. Introduction: To enhance anti-theft effectiveness, some vehicles are equipped with a steering lock. The steering lock is used to secure the car's steering shaft. It is integrated with the ignition lock and installed under the steering wheel, controlled by the key. After the ignition lock cuts off the ignition circuit and stops the engine, turning the ignition key to the extreme left position will extend the lock tongue into the steering shaft groove, mechanically locking the car's steering shaft. 2. Types: A car anti-theft device is installed in the vehicle to increase the difficulty and time required for theft, acting as a guardian for the car. By connecting the anti-theft device to the car's electrical circuit, it can prevent theft, intrusion, and protect the vehicle while enabling various functions of the anti-theft device. With advancements in technology, to counter increasingly sophisticated theft methods, various types and structures of anti-theft devices have been developed. These devices can be categorized into four main types: mechanical, chip-based, electronic, and network-based.

What is the reason for the truck bouncing while running?

It is probably because the tire pressure is too high. Here is an introduction to the relationship between car tire pressure and car performance: 1. Tire pressure and load capacity: Tire pressure is an indicator of a car's load capacity. The tire pressure of a car determines its load capacity. The higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity, provided that the tire pressure is within the standard range. 2. The relationship between tire pressure and car power: When the tire is running on a horizontal road, it needs to overcome the resistance of the ground and air. When the tire pressure decreases, the rolling resistance coefficient increases rapidly, the tire rolls and deforms, and fuel consumption rises. Appropriate tire pressure is a guarantee of good car power. 3. The relationship between tire pressure and car ride comfort: The ride comfort of a car is directly related to the comfort of passengers. Appropriate tire pressure can bring better comfort to passengers. When the tire pressure of a car is too high, the tire becomes hard, the vibration frequency of the vehicle increases, and the ride comfort deteriorates. Proper adjustment of tire pressure ensures the ride comfort of the tire.
