Is it necessary to repair a small scratch on the wheel hub?

Whether to repair a scratch on the wheel hub depends on the extent of the damage. Here are specific details about the degree of wheel hub damage: 1. No extension to the inner side of the wheel hub: Carefully check if the scratch extends to the inner side of the wheel hub. If it does not, it means you only need to use paint thinner to gently wipe around the scratch for simple repair and remove dirt. 2. Deep scratch on the wheel hub: Dirt near the scratch is difficult to clean. 3. Repairing the scratch: Before repairing the wheel hub scratch, use tape to cover the undamaged areas to avoid accidentally painting unrelated parts. After trimming the brush tip, apply touch-up paint and let it dry slightly, which will cause it to shrink. After painting, let it dry completely. Once dry, use waterproof paper soaked in soapy water to smooth the surface. After wiping with waterproof paper, use a compound to restore shine, and then apply wax.

What is the difference between No. 0 gasoline and No. 92 gasoline?

No. 0 is diesel, not gasoline. Gasoline has a higher octane rating and is classified into No. 89, No. 92, and No. 95 based on the octane level. There is no No. 0 gasoline. Diesel is a light petroleum product and a complex hydrocarbon mixture, serving as fuel for diesel engines. It is mainly composed of diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. Below are the characteristics of diesel: 1. Diesel has a higher carbon content compared to gasoline: It also has a higher density, which means that the same mass of diesel will burn longer, in other words, diesel is more "fuel-efficient" than gasoline; 2. Diesel has a lower auto-ignition point: Therefore, diesel engines use compression ignition, eliminating the need for spark plugs to ignite. By compressing air to raise the temperature to the diesel's ignition point and then injecting diesel, it can combust on its own; 3. Diesel is less volatile: It offers greater power and excellent fuel economy performance.

Is it mandatory to purchase comprehensive insurance for the first year when buying a new car?

It is not mandatory to purchase comprehensive insurance for the first year when buying a new car. There are no regulations requiring comprehensive insurance; the only compulsory purchase is compulsory traffic insurance and the payment of vehicle and vessel tax. However, other commercial insurances are not mandatory. New car owners may opt for comprehensive insurance in the first year to protect their vehicles, often entrusting 4S shops to handle it. Below is a detailed introduction to commercial vehicle insurances: 1. Vehicle Damage Insurance: Covers losses caused by natural disasters and accidents, recommended for new drivers. 2. Third-Party Liability Insurance: Covers losses due to third-party injuries or deaths caused by the owner, a must-have for protection. 3. No-Deductible Insurance: An add-on that transfers the owner's liability to the insurance company, reducing losses; recommended if both Vehicle Damage and Third-Party Liability insurances are purchased. 4. Theft and Robbery Insurance: Covers damages from vehicle theft or robbery, recommended for owners without garages. 5. Passenger Liability Insurance: Covers losses of drivers and passengers due to accidents, usually charged per seat; recommended for new drivers or family vehicles. 6. Spontaneous Combustion Insurance: Covers losses from fires caused by vehicle electrical or wiring issues, suitable for older vehicles. 7. Glass Breakage Insurance: Covers separate breakage of windshield or window glass; recommended for vehicles frequently in unsafe areas due to high replacement costs. 8.

Is a license plate required to apply for ETC?

A license plate is required to apply for ETC. According to the "Implementation Plan for Accelerating the Application of Electronic Non-stop Toll Collection on Expressways" issued by the Ministry of Transport, the following documents are needed: the original valid ID card of the vehicle owner, the original and a copy of the vehicle registration certificate (showing the most recent annual inspection stamp). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, you will also need to prepare a debit or credit card from the respective bank. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the funds as a deposit when binding ETC with a debit card. Since ETC is linked to the vehicle, the vehicle information must be complete. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); a copy of the organization code certificate or business license (with official seal); the agent's original ID card; the original vehicle registration certificate; the vehicle for which ETC is to be applied. You can also apply online: Since various banks have their own online services and platforms, to facilitate vehicle owners, online ETC application services have been launched, allowing you to apply without leaving your home. ETC billing principle: There are one or more ETC lanes on highways. Communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane enables automatic toll deduction via computer network technology linked to the bank. This allows vehicles to pass through toll stations without stopping, based on the principle of "pass first, pay later." Benefits of installing ETC: Saves time: eliminates the hassle of waiting in queues;

What is the difference between CH oil and CI oil?

Each subsequent letter represents a higher quality grade of oil. In other words, the CI grade is higher than the CH grade. 2. Different performance: With each increase in the oil quality grade letter, the performance is superior to the previous one. Whether it is the stability of the oil (detergency and dispersancy) or the protection performance for the internal engine (anti-corrosion and anti-oxidation), CI grade oil is better.
