Abstract
A lubricant composition suitable for use in engines fueled by gasoline or biorenewable fuels or both, comprising an oil of lubricating viscosity and a dispersant system is disclosed herein. Also disclosed is an emulsion composition comprising a biorenewable fuel, an oil of lubricant viscosity, and a dispersant system. A method of reducing aqueous separation in an emulsion composition is also disclosed.
Claims25
A lubricant composition suitable for use in engines fueled by gasoline or biorenewable fuels or both, comprising:
- (a) an oil of lubricating viscosity, and
- (b) a dispersant system comprising at least one dispersant selected from the group consisting of hydrocarbyl-substituted succinimides, hydrocarbyl-substituted amines, and Mannich base adducts derived from a hydrocarbyl-substituted phenol condensed with an aldehyde and an amine.
- wherein the lubricant composition forms a stable emulsion as compared to a lubricant composition devoid of the dispersant.
An emulsion composition comprising:
- (a) a biorenewable fuel;
- (b) an oil of lubricant viscosity;
- and
- (c) a dispersant system comprising at least one dispersant selected from the group consisting of hydrocarbyl-substituted succinimides, hydrocarbyl-substituted amines, or Mannich base adducts derived from a hydrocarbyl-substituted phenol condensed with an aldehyde and an amine.
1 more element
A method of reducing aqueous separation in an emulsion composition comprising:
- providing an emulsion composition comprising a biorenewable fuel and an oil of lubricating viscosity;
- and
- providing to said emulsion composition a dispersant system comprising at least one dispersant selected from the group consisting of hydrocarbyl-substituted succinimides, hydrocarbyl-substituted amines, or Mannich base adducts derived from a hydrocarbyl-substituted phenol condensed with an aldehyde and an amine.
