It has been found that the occurrence of maximum VI depends on the lube oil used and the type and concentration of viscosity index improver. After all, not everyone instantly understands approvals, specifications and viscosities. VI of blended oils, made from the lube oils (Servoneum 100, Servopress 68, Servomesh SP 220, and Servocut 335) by the addition of MMA, PBR, and Polyisoprene-cis, has shown the potential to reach the maximum value. or Which transmission oil, the LIQUI MOLY Oil Guide has the answer. The enhancement of VI of lube oils (Servoneum 100, Servopress 68, Servomesh SP 220, and Servocut 335) by the addition of viscosity index improvers (Methylmethacry-late (MMA), Polybutadiene rubber (PBR), and Polyisoprene-cis) has been studied. Viscosity Index improvers are added in the lube oils to reach the desired Viscosity Index (VI). This video is focused on solving the numerical problems based on calculation of viscosity index of lubricant.viscosityviscosityindexviscosityandviscosityi. Examples are power steering fluid, aircraft piston engine oils, modern internal-combustion engines, turbine engine oils (stationary and aircraft), and industrial gear oils. Standard ASTM D2270 Calculates Viscosity Index by Measuring the Kinetic Viscosity of Liquids at 40 and 100C and ASTM D567 Method for Calculating Viscosity Index from Viscosity at 100F and 210F. Viscosity Index (VI) improver has found its largest commercial applications as additives to engine oils. Engine oils are widely used for lubrication purposes in automobile and related industries.
