Abstract:
The invention relates to grease compositions containing high viscosity index polyalphaolefins (HVI-PAO) and polyurea thickeners. The use of HVI-PAOs and polyurea thickeners in a bi-modal base stock grease application provides favorable frictional properties and improved overall performance.
