Is 30,000 kilometers a major or minor maintenance?

Thirty thousand kilometers is considered a major maintenance. Generally, the maintenance items for a car at 30,000 kilometers include changing the engine oil, oil filter, air filter, fuel filter, cleaning the throttle body, replacing the spark plugs, etc. Some 4S shops may recommend additional maintenance items, which car owners can consider and decide based on actual conditions. Below are the relevant details: 1. Changing the engine oil and oil filter: Replacing the engine oil and oil filter is a mandatory item. Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of the engine oil is significantly shortened, and its performance greatly deteriorates. Over time, it will no longer protect the engine. The oil filter prevents impurities from mixing into the oil, which can cause oxidation and produce sludge that clogs the oil passages. The engine oil and oil filter should be replaced simultaneously. The air filter should be replaced every 10,000 to 15,000 kilometers, and the fuel filter should be replaced every 30,000 kilometers. 2. Cleaning the throttle body: Cleaning the throttle body is necessary at the 30,000-kilometer maintenance, but it is unnecessary before this mileage and can be declined. By 30,000 kilometers, the car has been driven for a considerable period, and the throttle body will have accumulated significant carbon deposits, leading to a reduced throttle opening and symptoms such as unstable idling and sluggish acceleration. If the car owner notices a drop in power during this period, they should consider inspecting the throttle body and spark plugs during maintenance. 3. Replacing the spark plugs: The spark plugs should also be replaced at 30,000 kilometers, provided they haven't been replaced before. At this mileage, the spark plugs haven't completely failed, but their ignition performance has significantly declined, directly affecting the engine's power, performance, and fuel consumption. If the car is running smoothly, the replacement can be delayed by another 10,000 kilometers. 4. Other items: Besides these items, the 30,000-kilometer maintenance also involves inspections and maintenance of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.

What are the differences between steel wheels and aluminum wheels?

The differences between steel wheels and aluminum wheels are as follows: 1. Material: Steel wheels have good toughness but poor hardness, while aluminum alloy wheels are the opposite, with good hardness but poor toughness. Due to the manufacturing materials and processes, steel wheels have poor stability at high speeds, whereas aluminum alloy wheels perform well in terms of stability at high speeds. Additionally, aluminum alloy wheels excel in acceleration and heat dissipation. 2. Usage: Although aluminum alloy wheels outperform steel wheels in overall performance, their cost is relatively higher. Replacing a set of standard aluminum alloy wheels can cost thousands of yuan. Moreover, the maintenance of aluminum alloy wheels is more complicated compared to steel wheels. Steel wheels usually come with plastic wheel covers. There are many stylish wheel covers available on the market, and if matched appropriately, they can achieve a similar aesthetic effect as aluminum alloy wheels.

When reversing, if the steering wheel is turned to the right, does the rear of the car also move to the right?

When reversing, turning the steering wheel to the right will cause the rear of the car to move to the right, and turning it to the left will cause the rear to move to the left. If moving forward, the opposite is true: turning the steering wheel to the left while moving forward will cause the rear of the car to move to the right, and turning it to the right will cause the rear to move to the left. When entering a parking lot to park, first assess the width of the parking space, check for any obstacles behind, whether there are cars parked on either side, and whether the length is suitable for your vehicle. If visibility is poor at night, step out to observe the exact position before reversing. Whenever possible, choose to reverse from the left side (if conditions permit). The left side makes it easier for the driver to observe. During the reversing process, first look behind, then pay attention to the side mirrors. The horizontal distance on the right side should be slightly larger than on the left. Be mindful of both the front and rear when reversing. When reversing into a parking space, situations may arise where, due to limited surrounding space and the addition of steering while reversing, the driver focuses solely on the rear of the car and neglects the front, leading to side scrapes on the front of the car. This happens because, during the turning process, the turning radius of the front wheels is larger than that of the rear wheels. As a result, when reversing, the front of the car swings outward, causing side scrapes on the front. Therefore, when reversing, it is essential to be aware of both the front and rear, ensuring full attention to both ends.
