Abstract
A silicone modified lubricant includes a Group I, II, III, IV or V base oil in combination with a minor amount of a silicone oil. Further, the lubricant includes a dispersant such as a dispersant olefin copolymer which maintains the silicone oil dispersed in the base oil. The silicone oil reduces the surface tension of the lubricant thereby reducing power loss. Preferably the lubricant formation has a surface tension less than 28 mN/m, making it particularly suitable for dip lubrication systems.
