How is 5W30 formulated?
Thread Content
Are there any guys in the group who are involved in formulating lubricants? How is 5W30 created? Could you explain it roughly?
The viscosity of 5W30 at 100 degrees is 9.3–12.5 cSt; for blending, base oils with viscosities of 4 and 6 cSt are used, along with additives, thickeners, and antifreeze agents, and everything is mixed evenly at around 50 degrees
The viscosity of 5W30 at 100 degrees Celsius is 9.3–12.6 cSt. For blending, base oils of type II with viscosities of 4 and 6 cSt are used; additives such as compounding agents, viscosity modifiers, and antifreeze agents are then added, and the mixture is stirred evenly at around 50–60 degrees Celsius
