Viscosity Index Improvers and Thickeners

Abstract

Early in the history of the lubricants industry, the viscosity index (VI) was an important measure of quality, providing an indication of the potential of an oil for application over a wide temperature range. Pennsylvania grade oils (∼ 100 VI) were the standard against which all others were measured. Hydrogenation and solvent extraction were developed to upgrade poorer quality crudes, but the refinery technology of the 1930s had a practical VI ceiling of about 110 to 115.
