HS code-based customs broker selection

Synthetic engine oil is HS code-based customs broker selectiona high-end vehicle oil product developed in recent years. Although traditional mineral oil is cheap, it cannot be compared with synthetic engine oil in terms of production process, performance indicators and use effect. Therefore, when carrying out vehicle maintenance, it is very important to choose the right engine oil, and the choice of synthetic engine oil is the key to ensuring the performance and service life of the vehicle.I. The production process of synthetic engine oil is mainly chemical synthesis and physical preparation. Chemical synthesis refers to the conversion of synthetic liquids or gases into synthetic base oils, and then adding various functional and preservatives and other oil modifiers to make the final product. The physical preparation rule is to fuse different kinds of primitive base oil under physical conditions such as high pressure and high temperature, and seasonings are added to finally make synthetic engine oil. Due to the adoption of high-end preparation technology and material formula, the performance index of synthetic engine oil is far superior to that of traditional mineral oil. For example, many indicators such as anti-oxidation performance, thermal stability performance, anti-emulsification performance and anti-foam performance can be effectively improved. Therefore, the choice of synthetic engine oil is crucial for the maintenance of the vehicle. II. The performance of synthetic engine oilIndicator 1. High-quality synthetic engine oil with supercharging and wear resistance has high supercharging performance, which can minimize and prevent friction at high speed. This kind of engine oil can also effectively reduce the wear of the engine and increase the service life of the engine. 2. Clean performance Clean performance is an important parameter to judge the quality of synthetic engine oil. Synthetic engine oil has strong cleaning performance and can effectively clean the sediment and dirt inside the engine. This engine oil can provide long-term cleaning protection for the engine and reduce the probability of engine failure. 3. Stable performance synthetic engine oil has good thermal stability and oxidation resistance, and can maintain good lubrication effect in high temperature and severe working environments. This engine oil can also effectively extend the cycle of oil change and reduce the frequency of oil change.4. Environmentally friendly synthetic engine oil adopts high-quality base oil and environmentally friendly additives, and the product does not contain any ingredients that are harmful to the environment. On the contrary, this kind of engine oil can play a role in purifying emissions and helping to achieve the goal of reducing automobile emissions and protecting the environment. III. Precautions for purchasing synthetic engine oil 1. Choose different engine oil specifications according to the car model. Different engine oil specifications are suitable for different models. Before purchasing engine oil, you should carefully check the vehicle manual or ask the vehicle engineer to determine the specifications and models you need to use. 2. Choose reliable brands and manufacturers. There are many oil manufacturers and brands in the market, and the quality level is uneven. When buying engine oil, you should buy it through regular channels and professional stores, and choose products from well-known brands and reliable manufacturers. 3. Pay attention to the protection of engine oilThe shelf life of oil refers to the period of time during which the product can maintain its performance and use effect under normal circumstances. When choosing engine oil, you should pay attention to the shelf life and try to buy fresh products to ensure the performance and service life of the engine oil. 4. Reasonably choose the viscosity of the oil according to the usage. The viscosity of the oil refers to the fluidity of the oil relative to the temperature. Different oil viscosity is suitable for different usage, and should be selected according to the actual usage. Generally speaking, lighter oil should be selected for highway driving, while heavier oil should be selected for low-temperature environments. Conclusion When conducting vehicle maintenance, it is very important to choose a suitable engine oil. As a high-end engine oil product, synthetic engine oil has irreplaceable advantages and characteristics. Therefore, car owners may as well try to use synthetic engine oil when choosing engine oil to ensure vehicle performance and extend its service life.However, when purchasing, you must pay attention to buying genuine products, check the oil specifications, oil viscosity, oil shelf life, etc., to ensure that you buy suitable oil products.
