Engine oil pipe: How to choose the right engine oil?HS code-driven procurement strategies Engine oil is an important lubricant for the normal operation of the engine. It can effectively reduce wear and friction and extend the service life of the engine. But withWith the continuous updating and upgrading of engine technology, there are more and more types of engine oil on the market, which makes consumers a little dazled. So, how to choose the right engine oil? This article will analyze from the following aspects. First, understand the classification of engine oil. Engine oil can be divided into gasoline oil and diesel oil according to the occasion of use. The main components of gasoline oil are mineral oil and synthetic oil, which are suitable for gasoline engines and small diesel engines. Diesel oil, on the other hand, is relatively complex and divided into many grades and types. According to the API standard, diesel oil can be divided into different grades such as CF, CF-2, CG-4, CH-4, CI-4, CI-4 Plus, etc., and there are obvious differences between each grade. Therefore, when choosing engine oil, you must first understand your engine type and oil grade to ensure that the selected engine oil meets the requirements.Second, choosing a suitable viscosity level of engine oil is also an important factor to consider when choosing engine oil. The higher the viscosity level, the longer the oil film stays on the metal surface, the better the lubrication effect; the lower the viscosity level, the easier it is to reach the specified oil temperature when the engine starts and works, so the fuel consumption is lower. At present, the viscosity level of engine oil on the market is generally 5W-30, 5W-40, 10W-30, 10W-40, etc. Consumers can choose the suitable viscosity level according to their own car model and usage environment. Third, it is very important to pay attention to the quality certification of oil products. The quality certification of engine oil is directly related to the service life and performance of the engine. At present, the engine oil quality certification standards on the market mainly include API, ACEA, ILSAC, JASO, etc.When buying engine oil, consumers must pay attention to the quality certification of oil products, not just the price or brand. Fourth, paying attention to the brand and manufacturer of oil products and the brand and manufacturer also have a great impact on the quality and performance of engine oil. Well-known brands and professional manufacturers usually have more advanced technology and stricter manufacturing standards in product research and development and manufacturing. Therefore, consumers had better choose some reputable brands and manufacturers when choosing engine oil, so as to better protect their engines. In fact, choosing the right engine oil is not an easy thing, and many factors need to be considered. However, if you don't know which engine oil is best for your vehicle, please refer to the advice of the vehicle manufacturer or consult a professional car repairman. BesidesTimely replacement of engine oil is an important measure to protect the car engine. Regularly checking the quality and liquid level of engine oil not only helps to extend the life of the engine, but also avoids some unnecessary losses.
