This disclosure is directed to an additive package for a lubricant composition that provides improved compatibility with fluoropolymer seals. The additive package comprises a seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil and a seal compatibility additive. The seal compatibility additive improves the compatibility with fluoropolymer seals of the resultant lubricant composition.

Seal compatibility additive to improve fluoropolymer seal compatibility of lubricant compositions

This disclosure is directed to an additive package for a lubricant composition that provides improved fluoropolymer compatibility. The additive package comprises a halide seal compatibility additive and a second seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil, a halide seal compatibility additive, and a second seal compatibility additive. The halide seal compatibility and the second seal compatibility additive improves the fluoropolymer seal compatibility of the resultant lubricant composition.

Lubricating oil compositions containing a halide seal compatibility additive and a second seal compatibility additive

This disclosure is directed to an additive package for a lubricant composition that provides improved fluoropolymer compatibility. The additive package comprises an amine compound and a seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil, an amine compound, and a seal compatibility additive. The seal compatibility additive improves the fluoropolymer seal compatibility of the resultant lubricant composition.

Lubricating oil compositions containing seal compatibility additives and sterically hindered amines

A lubricant composition having improved non-Newtonian viscometrics includes at least 85 weight percent of a base oil and 1 to 15 weight percent of a lubricant additive. The additive itself includes 10 to 80 weight percent of a diluent oil and 30 to 80 weight percent of a random co-polymeric viscosity index improver. The viscosity index improver is the free-radical polymerization product of at least 5 to 15 weight percent methyl methacrylate and 5 to 95 weight percent of a C-Calkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C-Calkyl (meth)acrylate, and a free-radical initiator. The method also includes the steps of flowing the diluent oil into a reactor, flowing the methyl methacrylate and the C-Calkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.

Lubricant composition having improved non-Newtonian viscometrics

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 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.

Lubricant compositions comprising epoxide compounds

A lubricant composition is substantially free of water and includes a base oil present in an amount of greater than 85 parts by weight per 100 parts by weight of the lubricant composition, includes an antioxidant, and includes one or more alkylethercarboxylic acid corrosion inhibitor(s) present in an amount of from 0.01 to 1 weight percent based on a total weight of said lubricant composition. The one or more alkylethercarboxylic acid corrosion inhibitor(s) have the formula; wherein R is a straight or branched chain C-Calkyl group and n is a number of from 0 to 5.

Lubricant composition

The present invention is directed to the use of alkyl(meth)acrylate polymers or copolymers of the formula (I)In-Poly-(E)&#x2003;&#x2003;(I)as cold flow improvers in biodiesel fuel (or bio-fuel) and biodiesel compositions incorporating said polymers or copolymers, obtained by nitroxyl mediated controlled free radical polymerization,

Biodiesel cold flow improver

A lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula; In this formula, R is a straight or branched chain C6-C18 alkyl group and n is a number of from 0 to 5. The lubricant composition can be utilized in a method for reducing corrosion of a steel article. The method includes the steps of providing the base oil and providing the one or more alkylethercarboxylic acid corrosion inhibitor(s). The method also includes the step of combining the base oil and the one or more alkylethercarboxylic acid corrosion inhibitor(s) to form the lubricant composition including less than about 0.1 weight percent of the one or more alkylethercarboxylic acid corrosion inhibitor(s). The method further includes the step of applying the lubricant composition to the steel article wherein the steel article passes corrosion testing according to ASTM D 665 B.

The instant invention provides a lubricant composition having improved four-ball antiwear properties. The lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula: wherein R is a straight or branched chain C-Calkyl group and n is a number of from 0 to 5. The lubricant composition also includes an ashless antiwear additive including phosphorous. The four-ball antiwear properties are reported as an average diameter of wear scars pursuant to ASTM D4172. The average diameter of the wear scars resulting from the lubricant composition are at least 5% smaller than the average diameter of the wear scars resulting from a standard that includes the base oil and the antiwear additive and that is free of the one or more alkylethercarboxylic acid corrosion inhibitor(s).
