Two lubricants with the same VI may perform dramatically differently at low temperatures. Later used in many industrial applications from compressor, hydraulic, and turbine fluids to gear oils and metalworking fluids. Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. Water for liquid cooling comes from different sources. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. For other applications, PAOs safe and non-toxic nature allows them to be used where incidental food contact certification or kosher approval is necessary. Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. Polyalphaolefin plus TDS | ExxonMobil Product Solutions Some specifications have a low-temperature MRV requirement. All rights reserved. Cant find what youre looking for? The current trend toward lower viscosities, while providing for extended drain capabilities, does present an interesting challenge for base oils.
