Additives 2 – Bulk Oil Additives
Additives 2 – Bulk Oil Additives focuses on the core chemical technologies used to enhance the bulk properties of lubricating oils. These additives are not surface-active—they don’t primarily protect metal—but instead improve the fluid’s stability, performance, and behavior under changing temperature, pressure, and contamination conditions.
The course covers key additive categories such as viscosity index improvers, pour point depressants, antifoam agents, demulsifiers, and antioxidants. You’ll learn how each one functions, when it’s used, and how they interact with the rest of the formulation. You’ll also explore the critical role of antioxidants—both primary and secondary—in fighting oxidative degradation and extending oil life, as well as the use of metal deactivators to manage catalytic wear and varnish formation.
Whether you’re blending formulations, selecting lubricants for a demanding application, or interpreting lab data, this course will give you a clear understanding of how bulk oil additives influence fluid performance.
After completing this course, you will be able to:
- Identify the function and purpose of each bulk oil additive type
- Understand how viscosity index improvers help maintain performance across temperatures
- Explain the role of antioxidants in oil life extension
- Recognize how demulsifiers and antifoam additives support system reliability
- Apply this knowledge to formulation, selection, and analysis of lubricants
