Abstract: Provided are formulations, methods of making, and methods of using one or more Fischer-Tropsch Base Oils of the present invention in a low sulfur, low sulfated ash, and low phosphorus engine lubricant to enhance thermal stability of the lubricant as well as the high-temperature performance of an engine housing the lubricant.

Abstract: Provided are formulations, methods of making, and methods of using one or more Fischer-Tropsch Base Oils of the present invention in a low sulfur, low sulfated ash, and low phosphorus engine lubricant to enhance thermal stability of the lubricant as well as the high-temperature preformance of an engine housing the lubricant.

Abstract: Provided are formulations, methods of making, and methods of using one or more reaction products of polyisobutylenes and monounsaturated acylating agents of the present invention in a low sulfur, low sulfated ash, and low phosphorus lubricant to enhance piston cleanliness in internal combustion engines.

Abstract: The present invention provides engine lubricants for low emission diesel engines featuring low levels of ash, sulfur and phosphorus. Specifically, this invention provides a low emission diesel lubricant comprising from about 0 wt. % to about 1.2 wt. % ash; from about 0.1 wt. % to about 0.5 wt. % sulfur; and from about 0.02 wt. % to about 0.1 wt. % phosphorus. Said lubricant may also comprise a novel unsulfurized, carboxylate-containing additive for lubricating oils, comprising a mixture of alkaline earth metal salts (hydrocarbyl phenate/hydrocarbyl salicylate) and a reduced amount of unreacted hydrocarbyl phenols, in which said hydrocarbyl salicylate is primarily single-aromatic-ring hydrocarbyl salicylate. The invention also provides a method for producing said additive and said LEDL.

Abstract: This invention relates to a method of improving elastomer seal compatibility and dispersancy in an internal combustion engine by contacting the elastomer seal in the internal combustion engine with a lubricating oil composition comprising:
