Abstract: A copolymer including ethylene units and units of one or more C3-10 alpha-olefins. The copolymer has a number average molecular weight of less than 5,000 g/mol, as measured by GPC. The ethylene content of the copolymer is less than 80 mol %. At least 70% of molecules of the copolymer have an unsaturated group, and at least 70% of said unsaturated groups are located in a terminal vinylidene group or a tri-substituted isomer of a terminal vinylidene group. The copolymer has a crossover temperature of −20° C. or lower and/or a certain ethylene run length. Also disclosed are a method for making the copolymer and polyolefins plasticized with 1-40 wt % of the copolymer.

Abstract: A lubricating oil composition including a major amount of a base oil, one or more calcium-containing detergents to provide at least 1000 ppmw of calcium, and one or more silicon-containing compound(s) to provide at least 50 ppmw of silicon to the lubricating oil composition, all based on the total weight of the lubricating oil composition, wherein a ratio of ppmw of silicon provided by the one or more silicon-containing compound(s) to the lubricating oil composition to the ppmw of calcium provided by the one or more calcium-containing detergent(s) to the lubricating oil composition is from 0.02 to 1. Methods of using these compositions and silicon-containing detergents are also described.

Abstract: Ethylene-C3-C10 alpha olefin copolymers, dispersants and lubricating oils/fuel compositions incorporating dispersants, and related methods are generally described herein. The copolymer may comprise ethylene-derived units and C3-C10 alpha-olefin-derived units. The C3-C10 alpha-olefin-derived units may have a carbon number from three to ten. For example, the C3-C10 alpha-olefin-derived units may be propylene-derived units. The dispersants may be made from copolymers having low metal and/or fluorine contents.

Abstract: Particulate filters are used to remove particulate matter such as soot and ash in the emissions control systems of vehicles, including gasoline direct injection (GDI) engines. Methods are provided to predict the long-term performance and durability of emissions control systems having particulate filters. The methods account for factors such as thermal aging, soot accumulation and regeneration, and ash loading.

Abstract: Gasoline Direct Injection (GDI) engines require gasoline particulate filters (GPFs) as a key component of the emissions control system to reduce particulate emissions. GPFs are known to have poor initial performance, with performance increasing after the filter develops a cake. This poor initial performance make it impossible to accurately assess vehicle emissions performance at the mileage requirements for vehicle certification. Compositions and methods are disclosed to improve filtration efficiency in a fresh or low mileage GPF.
