1. Additives acting physically in the lubricant mass
1.1 Thickening additives
In addition to the viscosity-index-enhancing additives discussed at 4.2 , which thicken oils when hot while keeping them fluid when cold, there are products used mainly in industrial lubrication, which can be used to formulate lubricants with a higher viscosity than is possible with the available ranges of mineral and synthetic...

Economic data
Lubricant additives are commercially available either as elementary additives or base components or, increasingly, as pre-formulated additives known as "additive packages", "performance additives" or "packages".
The former are mainly used in the preparation of industrial oils, metalworking lubricants and greases, or as complementary additives...
