A composition comprises the reaction product of a dithiophosphate derivative and an amine. The reaction product is present in the composition in an amount of at least about 25 wt. %. The composition may include additional components. A method of forming the composition comprises the step of combining the dithiophosphate derivative and the amine to form the composition. A method of increasing thermal stability of a dithiophosphate derivative comprises the step of combining the dithiophosphate derivative and an amine. The dithiophosphate derivative can decompose to form hydrogen sulfide (H2S). However, the amine substantially prevents thermal decomposition of the dithiophosphate derivative. An example of the dithiophosphate derivative is 3-(di-isobutoxy-thiophosphorylsulfanyl)-2-methyl-propanoic acid. An example of the amine is ditridecyl amine. The composition can be used for a variety of applications. For example, the composition can be used as an antiwear compound/additive in lubricants, metalworking fluids, hydraulic fluids, etc.

A lubricant composition includes a base oil, an alkoxylated amide, an ester, and an anti-wear agent including phosphorus. The alkoxylated amide and ester have general formulas (I) and (II), respectively. The lubricant composition may be further defined as a racing oil composition. Also disclosed is a method for maximizing the effectiveness of a friction modifier in a racing oil composition thus increasing the fuel economy of a racing vehicle. The method includes providing the racing oil composition and lubricating an internal combustion engine of a racing vehicle to increase the fuel economy of the racing vehicle.

Alkoxylated amides, esters, and anti-wear agents in lubricant compositions and racing oil compositions

The present disclosure provides an additive package for a lubricant composition that includes an alkoxylated amide, an ester, and an anti-wear agent including phosphorus, molybdenum, or a combination thereof. The present disclosure also provides a lubricant composition that includes a base oil, the alkoxylated amide, the ester, and the anti-wear agent including phosphorus, molybdenum, or a combination thereof. The present disclosure further provides a method of lubricating an internal combustion engine for improving fuel economy.

Alkoxylated amides, esters, and anti-wear agents in lubricant compositions

This disclosure is directed to a lubricant composition having improved compatibility with fluoropolymer seals. The lubricant composition includes a base oil and a sulfonate ester. The disclosure is also directed to an additive package for a lubricant composition that provides improved compatibility with fluoropolymer seals. The additive package includes the sulfonate ester. The disclosure is also directed to a method of improving compatibility of a lubricant composition with a fluoropolymer seal disposed in an internal combustion engine. The sulfonate ester improves the compatibility with fluoropolymer seals of the resultant lubricant composition.

Sulfonate esters to improve fluoropolymer seal compatibility of lubricant compositions

A composition and method of improving the fuel economy of hydrocarbon fuel-powdered internal combustion engines. The composition contains a propoxylated and/or butoxylated reaction product of (a) at least one fatty acid, fatty acid ester, or mixture thereof and (b) a dialkanolamime. The composition is added to a hydrocarbon fuel in an amount of about 5 to about 2,000 ppm, based on the weight of the hydrocarbon fuel, to reduce friction within the engine and achieve an enhanced fuel economy.

Composition and method to improve the fuel economy of hydrocarbon fueled internal combustion engines

A lubricant composition including an epoxide compound is disclosed. An additive package including the epoxide compound is also disclosed. The epoxide compound of the lubricant composition acts to improve compatibility of the lubricant composition with a fluoropolymer seal and improve the total base number of the lubricant composition.
