Hybrid electric transmission fluid |
摘要 |
A dispersant additive composition, a lubricant composition containing the dispersant additive, a transmission containing the dispersant additive, and a method of providing a versatile lubricating fluid. The dispersant includes a reaction product of a hydrocarbyl substituted carboxylic acid or anhydride and an amine. The reaction product has a nitrogen content up to 10,000 ppm by weight, and a boron plus phosphorus to nitrogen ((B+P)/N) weight ratio of from 0:1 to about 0.8:1. The dispersant additive composition is effective to provide an electrical conductivity to a lubricant composition containing the dispersant additive composition and a metal detergent of less than about 1700 pS/m. |
