Abstract: 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.

Abstract: 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.

Abstract: A lubricant composition has an increased oxidation induction time. The lubricant composition includes a base oil present in an amount of greater than 85 parts by weight per 100 parts by weight of the lubricant composition. The lubricant composition also includes an antioxidant component including particular first, second, and third antioxidants.

Abstract: 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 C8-C10 alkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C8-C10 alkyl (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 C8-C10 alkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.

Abstract: 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.

Abstract: The present invention is directed to the use of alkyl(meth)acrylate polymers or copolymers of the formula (I) In-Poly-(E)y??(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, wherein In is the initiator fragment starting the polymerization reaction; E is an end group bearing at least one stable free nitroxyl radical, which is bound via an oxygen atom to the polymer or copolymer; or a group which results from a substitution or elimination reaction of the attached stable free nitroxyl radical; Poly is any polymer or copolymer formed from ethylenically unsaturated monomer(s); and y is a number 1 or greater than 1 indicating the average number of end groups E attached to Poly.
