There is provided a base oil additive comprising an ester of a palmitic acid, a method of forming the base oil additive, a lubricating oil composition comprising the base oil additive and a method of modifying a property of a base oil.

The present invention relates to a lubricating mixture, which contains glycerides of natural origin and fatty acid alkyl esters. The glycerides are at least partly mono and/or diglycerides which form a mass fraction of 10% in the mixture. In a temperature range from 10 C. to at least 15 C. the mixture has a liquid phase with a solid fraction of 1 vol. %, which is formed from a fraction of glycerides and/or fatty acid alkyl esters. The mixture can be formed entirely from renewable raw materials, has a high viscosity index and is particularly suitable as a lubricant for use in gearings, electric motors or internal combustion engines.

The present invention provides a cutting method comprising a cutting step of cutting a workpiece material with a cutting tool to thereby form a through-groove in the workpiece material, wherein in the cutting step, the through-groove is formed in the workpiece material by cutting the workpiece material with the cutting tool while contacting a cut-assisting lubricant with the contact portion of the cutting tool with the workpiece material and/or the contact portion of the workpiece material with the cutting tool, and the workpiece material comprises a fiber reinforced composite material.

This application relates to branched diester compositions that can be used as a base stock for lubricant applications, or as a base stock blend component for use in a finished lubricant or for particular applications, and methods for making the same.

A method for improving oxidation stability and viscosity control, while maintaining or improving cleanliness performance and deposit control, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and a mixture of (i) at least one detergent, and (ii) at least one antioxidant, or a mixture of (i) at least one detergent, (ii) at least one dispersant, and (iii) at least one antioxidant, as minor components. The at least one detergent comprises a sulfonate detergent, the at least one dispersant comprises a borated dispersant, and the at least one antioxidant includes an alkylated diphenylamine. The engine or other mechanical component is lubricated with the lubricating oil operating in the presence of biodiesel fuel. A lubricating oil formulated with the above major and minor components.

The invention has an object of providing ethylene/-olefin copolymers having high randomness and a small number of double bonds in the copolymers. The ethylene/-olefin copolymers of the invention are obtained by copolymerizing ethylene and an -olefin having 3 to 20 carbon atoms in the presence of an olefin polymerization catalyst which includes a bridged metallocene compound (A) represented by the formula [I], and at least one compound (B) selected from organometallic compounds (B-1), organoaluminum oxy compounds (B-2) and compounds (B-3) capable of reacting with the bridged metallocene compound (A) to form an ion pair, and have a specific weight average molecular weight, a specific molecular weight distribution, a specific glass transition point and a specific value B. ##STR00001##

The present invention relates to a lubricating oil composition comprising polyglycerol partial esters of polyfunctional carboxylic acids and saturated or unsaturated, linear or branched fatty acids and/or poly(hydroxystearic acid) and the use thereof to lubricate an engine and reduce friction.

The present invention relates to a lubricating composition comprising: from 0.1% to 30% by weight, with respect to the total weight of the composition, of at least one 2-octanol monoester of formula R1-C(?O)OR2, in which R1 denotes an alkyl group comprising from 8 to 36 carbon atoms and R2 denotes 1-methylheptyl, and at least one base oil.

The invention also relates to the use of the 2-octanol monoester as additive in a lubricating composition.
