Brief Overview: Viscosity and its Grading
This lecture will illustrate the concept of viscosity and different viscosity classifications, with a particular focus on viscosity grades of engine oil and industrial oil. A brief mechanism about viscosity index improver will be explained. Viscosity comparison table gives approximate equivalence of values for a typical conventional fluid.

Topics Covered

  • Concept of viscosity and classification

  • SAE viscosity grades

  • ISO viscosity grades

  • Viscosity index

  • Viscosity comparison table

Brief Overview: Marine Lubricants
This lecture will illustrate the concept of marine lubrication and classification of marine lubricants – focusing on the performance requirements of three different marine lubricants. It will cover trends in marine lubricants driven by emission regulation such as IMO 2020. The selection of marine lubricants will also be explained according to different parameters.

Topics Covered

  • Concept of marine lubricant

  • Classification of marine lubricants

  • The performance of marine lubricants

  • Trend of marine lubricants

  • The selection of marine lubricants
