How to accurately use automotive lubricants The above-mentioned 0W-30, 5W-40, 10W-40 these digital combinations called the viscosity grade of the lubricant, the viscosity grade of the engine oil is usually formulated with reference to the standard of SAE J300 of the International Society of Automotive EngineersIs also an important indicator when we pick engine lubricants, in which the W represents the English word winter (Winter), the front with the number and the letter W viscosity is called low temperature power viscosity, also known as winter viscosity. Also represents the bottle of lubricating oil in low temperature conditions in the engine fluidity is good, so the smaller the number of words in front of W, on behalf of it in the low temperature environment can still play a relatively good protection and lubrication of the engine, the larger the value on behalf of it is not suitable for use in the low temperature environment.W English letter after the viscosity refers to the lubricant in 100 ° kinematic viscosity, also known as high temperature kinematic viscosity. The two numbers after W represent the consistency of the lubricant when working in a high-temperature environment, and the larger the value, the higher the consistency. 2023-04-30
