GEAR AND ENGINE OILS WITH REDUCED SURFACE TENSION |
| 摘要 |
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° C. (about 500 cSt at 25° 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. |

1. A gear oil comprising:
a base oil selected from the group consisting of Group I-IV base oils; an amount of silicone oil effective to decrease the surface tension of said base oil to less than 28 mN/m, said oil having a viscosity less than 500 cSt at 25° C. |
