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.

Silicone modified lubricant

A gear or engine oil or other type of lubricant, which effectively reduces churning losses in a dip lubrication system or any lubrication system where churning loss occur has a surface tension less than 28 mN/m and viscosity less than 400 mPa-sec at 25&#xb0; C. (about 500 cSt at 25&#xb0; C.). Formulations include Group I-IV base oil, in combination with an amount of silicone oil effective to decrease the surface tension of the oil, thereby reducing churning losses. When the base oil is prominently Group III, the coefficient of friction of the gear oil is also reduced.
