BLEND COMPRISING GROUP III AND GROUP IV BASESTOCKS

摘要

The invention relates to compositions comprising a blend of Group III basestocks and low volatility, low viscosity PAO basestocks. The blend is particularly useful for preparing finished lubricants that meet or even exceed the criteria for SAE Grade OW multi-grade engine oils. The combination of these low volatility, low viscosity PAOs with Group III basestocks provide, in embodiments, the necessary performance criteria in automatic transmission fluids, automotive or industrial gear oils, hydraulic fluids, or any other high performance lubricant requiring a combination of excellent low fluidity and low volatility.
