How did cold winters hit trucks choose winter oil?
Just over the eleventh holiday period, cold air hit many parts of the country. The temperature in some cities in the north suddenly dropped, and some places in the north even had snow. As the winter gets closer, we must begin to prepare the truck for oil changes. How to choose the winter lubricant In winter, when the temperature is lowered, the fluidity of the lubricant is deteriorated. If no attention is paid to replacement, trucks in cold regions in the north are prone to start-up difficulties and increase fuel consumption. There are two main metrics when selecting a lubricant: the oil level and the viscosity level, first select the oil level and then select the viscosity level. Oil performance If you pay attention to the oil drum when you change the oil, you may have seen symbols such as CH-4 or CJ-4 on the oil lubrication barrel. What does this mean? Lubricant quality level These represent the level of lubricating oil. The "S" series represents the gasoline engine oil; the "C" series represents the diesel engine oil. When the two letters "S" and "C" are present at the same time, it means that the engine oil is of the general type for diesel engines. At the same time, it is also divided into different levels. The higher the level, the better the oil quality. The four diesel engines available for CI grade lubricants. 2. Viscosity level In addition, you will find SAE 15W-40 and other symbols on the drum. What does it mean? The 15W in front indicates the low-temperature viscosity grade, which is divided into 0W, 5W, 10W, 15W, 20W, 25W. Good; behind the 40 indicates the viscosity level at 100 °C, divided into 20, 30, 40, 50, 60, the greater the number, the higher the viscosity. The performance of oil at different temperatures Only consider the use of oil in high temperature or low temperature environment such as SAE 40, 50, 10W, etc. as a single-grade viscosity oil. Considering the high temperature performance, the oil with better low temperature performance is called multi-grade viscous engine oil, such as SAE 5W-40 and 15W-40. At present, it is mostly multi-grade viscosity oil. SAE viscosity grade Considering the cold climate in the north, most regions can choose SAE 10W-30 or SAE 5W-40 grade oil. Knowing this knowledge, you can choose the fuel according to your own situation! For example, your truck is the national common rail model, the lowest temperature in winter is around -20 degrees, you can choose CI-4 5W-40 it! 30Mm Picatinny Scope Rings,Hunting Scope Mount,Outdoor Camping 30Mm Rifle Scope,Outdoor Hunting Scope Mount Guangzhou Miaozhun Jie Trade Co.,Ltd. , https://www.focuhunter.shop
