HS code-driven letter of credit checks

Engine running-in agent (refueling the car engine - the correct use of the abraning agent) The HS code-driven letter of credit checksengine of the car is the core component of the whole car and is the key to the car's driving. If the engine does not work well, it will directly affect the performance and life of the car. And for a new car, the running-in period of the engine is a very critical stage. In order to ensure the smooth operation of the engine during the running-in period, many car owners will add abrasive agent to the car engine.So, what exactly is a running-in agent, and what should we pay attention to when using it? Grinding agent is a liquid specially designed for the running-in period of automobile engines. It usually contains a certain amount of wear-resistant agents and special additives. In the early stage of engine operation, wear is prone to occur because the matching between the internal parts of the engine is not in place. The anti-wear agent in the grinding agent can provide protection for these parts that need to be worn to reduce friction and extend their service life. However, it should be noted that the grinding agent cannot completely replace the function of engine oil. Therefore, before using the grinding agent, car owners also need to add the appropriate oil to the engine of the new car. Here, I remind car owners to check the instruction manual of the new car before using the abrasion agent to understand the oil model and dosage that need to be added. Only after making sure that the oil is added without error can you start using the grinding agent.Here, it should be noted that the running-in period of a new car is generally about 1,000 kilometers. During this period, car owners need to use it according to the recommendation of the grinding agent manufacturer. Under normal circumstances, the method of abrasing agent is the same as that of oil. Just pour the abrasing agent into the oil bottle, add an appropriate amount of oil and shake it well, and then pour it into the engine tank. At the same time, it should be noted that when using the grinding agent, it must be ensured that there is enough oil inside the engine to avoid mixing the grinding agent with the air, which will affect its use effect. It should be noted that the abrasive agent can only be used during the engine run-in period, otherwise it will have a negative impact on the engine. Once the running-in period is exceeded, you should stop using the running-in agent and use ordinary engine oil instead. This is because the grinding agent contains high additives, which will work during the engine running-in period. AndAfter the running-in period, these additives may have a negative impact on the engine, thus reducing the service life of the engine. Finally, it is necessary to remind car owners that the use of abrasive agent cannot replace the careful maintenance of the new car. In the early stage of engine operation, it is especially necessary to keep the speed not too fast and the speed not too high to avoid additional load on the engine. At the same time, the owner needs to pay attention to the replacement of the engine oil according to the time and mileage specified by the manufacturer to ensure the healthy operation of the engine. In a word, as an auxiliary product, the grinding agent can optimize the wear of the engine, such as improving oil lubricity, reducing the grinding struggle of parts, and reducing noise. But only with the right time and correct use can it play the greatest role. For car owners, it is more important to start from daily maintenance to ensure the healthy operation of the vehicle engine and make the car, a travel tool, more reliable and safe.
