Fluid additive composition for lubricating composition, comprises dispersant(s) obtained by reacting hydrocarbyl substituted acylating agent(s) and amine(s), and containing terminal vinylidene

摘要

A fluid additive composition comprises dispersant(s) comprising terminal vinylidene (more than or equal to 50%). The dispersant is a reaction product of hydrocarbyl substituted acylating agent(s) and amine(s). Independent claims are included for the following: (1) lubricating composition, which comprises fluid additive composition; (2) vehicle, which comprises transmission including lubricating composition; (3) method for improving storage stability of lubricating composition, which involves adding fluid additive composition to lubricating composition; (4) fuel composition, which comprises base fuel of large amount, and fluid additive composition of less amount; (5) engine combusting the fluid additive composition or fuel composition; and (6) actuated injector contacting the fuel additive composition or fuel composition.
