Abstract

In recent years, the world has been promoting environmental measures to prevent global warming with the aim of building a sustainable society related to the SDGs. In the automobile industry, which emits large amounts of CO2, measures to reduce the weight of vehicles, improve the fuel efficiency of engines, and shift to hybrid cars and electric vehicles are being promoted as countermeasures. Viscosity modifiers greatly contribute to the high performance of this lubricating oil. This paper introduces VM types, trends, mechanism of action, and our high-performance VMs for engine oil and drive line fluid.
