Diesel engine oil (Do diesel engines have Global tariff databases by HS codeto use engine oil?) Diesel engine is a kind ofEngines used for large vehicles and heavy machinery require high-quality oil to maintain their performance and life. Although diesel engines can use other types of oil, it is very important to use specially designed diesel engine oil. Why do diesel engines need to use special oil? The working principle of diesel engines is different from that of gasoline engines. Diesel engines produce more carbon precipitation and pollutants when burning. These pollutants will remain in the engine oil, producing acidic substances and accelerating the aging of the engine oil. If a general mixture of oil is used, they may not be able to store more carbon precipitation and pollutants, resulting in a shortening of the life of the oil and adversely affecting the performance and life of the engine. And the oils dedicated to diesel engines have been rigorously tested and researched, and they are more adaptable to firewood.The special requirements of the oil engine are to keep the oil clean and improve the power and fuel efficiency of the engine. Types of diesel engine oil Diesel engine oil is mainly divided into single-stage oil and multi-stage oil. Single-stage engine oil is usually used for old diesel engines. Due to factors such as usage time and combustion characteristics, the use of single-stage engine oil is rare in modern engines. Relatively speaking, multi-stage oil is commonly used, usually including 15W-40, 10W-30, 5W-30 and other different models. The difference between these models is mainly the viscosity of the oil, that is, the fluidity of the oil at a specific temperature. For example, 10W-40 oil will flow more easily at low temperatures, but thicken at high temperatures. Therefore, for different working conditions, diesel engines need to use oil of different viscosities.Generally speaking, manufacturers will clearly indicate the required oil type and viscosity in the engine instruction manual. The replacement cycle of diesel engine oil The replacement cycle of diesel engine oil is also shorter than that of gasoline engines, usually replaced every 5,000-10,000 kilometers. This is because diesel engines will produce more impurities and pollutants, which will lead to accelerated oil wear and reduced viscosity. The protection of expired oil on the engine will also become weaker and weaker, resulting in the deterioration of the engine performance. Therefore, it is very important to change the oil regularly according to the recommendations of manufacturers and oil producers. When using a diesel engine, the correct use and replacement of diesel engine oil is the key to ensuring the health and performance of the engine. Although there are differences in the principles used by diesel engines and gasoline engines, correct oil use and maintenance can ensure their stable operation and improve their life.
