In the process of maintaining your car’s engine, the choice of engine oil is crucial. Oil viscosity is an important indicator of engine oil quality and has a decisive impact on engine performance and life. So, which engine oil has the best viscosity? This article will take you to explore the secrets of engine oil… Read more

The generation of bubbles is often a thorny problem in many industries and daily life. Excessive foam will affect the smooth progress of the production process, reduce product quality, and even cause machine damage. To prevent foaming in oil, you can use oil inhibitors designed specifically for this purpose. A common oil inhibitor that helps… Read more

Hydraulic oils are graded according to their viscosity, an important property that determines their performance in hydraulic systems. Viscosity is often expressed as a number, such as ISO 32, ISO 46, or ISO 68. The higher the number, the thicker the oil. In hydraulic systems, the viscosity of the oil plays a critical role in… Read more

Demulsifiers, also called demulsifiers, are additives used in oils to dissolve and prevent emulsions from forming. An emulsion is a droplet of one liquid dispersed in another immiscible liquid. In the case of oils, an emulsion is when water is mixed with oil to form a stable emulsion. Demulsifiers work by breaking down the interface… Read more

Pour point is the temperature at which a petroleum product changes from liquid to solid under test conditions. Lowering the pour point of petroleum products can improve their low-temperature fluidity and pumpability. It is generally believed that the change in pour point can be used as one of the low-temperature flow performance indicators of oil… Read more

Pour point is a term referring to the lowest temperature at which a liquid lubricant, such as oil, can flow under specific conditions. At this temperature, the lubricant becomes too thick and viscous, making it difficult to pour or flow. Pour point is an important characteristic to consider in lubricants, especially those used in cold… Read more

PIBSI stands for polyisobutylene succinimide, but it is not used as a lubricant itself. Instead, PIBSI is used as a dispersant additive in lubricating oils. It helps keep dirt, sludge, and other contaminants suspended in the oil, preventing them from building up and causing engine damage. PIBSI also helps improve the overall cleanliness and efficiency… Read more

Pour point and freezing point are two different physical concepts. They both involve the phase change of liquids, but there are some differences. Pour point is the critical temperature at which a liquid begins to change from liquid to solid phase under a certain pressure. In other words, when the temperature of a liquid drops… Read more

Pour point and flash point are two common properties of petroleum products, and there are obvious differences in their definitions and measurement methods. Pour point refers to the minimum temperature at which a petroleum product flows when cooled to the sample under specified test conditions. Its unit is degrees Celsius. Pour point is an important… Read more
