A content of the component (B) is less than 0.60 mass % based on a total amount of the lubricating oil composition, a content ratio [B/N] by mass of boron atoms to nitrogen atoms derived from the component (C) is 0.35 or more, and a content of boron atoms derived from the component (C) is 300 ppm by mass or less based on the total amount of the lubricating oil composition.

A lubricating oil composition for internal combustion engines, including: (A) a lubricating base oil; and (B) a metal-based detergent, wherein the component (B) contains: (B1) a calcium-based detergent in which a content of calcium based on a total mass of the composition is within a specific range; and (B2) a magnesium-based detergent in which a content of magnesium based on the total mass of the composition is within a specific range, the component (B1) contains (B1-1) a calcium-based detergent containing boron and calcium, a content of boron based on the total mass of the composition is 1000 mass ppm or less, a ratio (B(B1)/Ca(B1)) of B(B1) to Ca(B1) is 0.15 or more and 0.35 or less, and a ratio (B(B1)/[Ca(B1)+Mg(B2)]) of B(B1) to a total amount (Ca(B1)+Mg(B2)) of Ca(B1) and Mg(B2) is 0.13 or more and 0.29 or less.

A problem is to provide a heat treating oil composition containing a sulfur compound that is excellent in brightness of a metal material after a heat treatment, such as quenching, and in storage stability. The problem is solved by a heat treating oil composition containing one or more kinds of base oils (A) selected from the group consisting of a mineral oil (A1), a synthetic oil (A2), and a vegetable oil (A3), and a sulfur compound (B), the sulfur compound (B) containing one or more kinds selected from the group consisting of a particular sulfide compound (B1), a particular sulfide compound (B2), and a particular thiazole compound (B3).

A fluid contains a base oil consisting of an alcohol-initiated polyalkylene glycol where polyalkylene glycol component is selected from a homopolymer of 1,2-butylene oxide and copolymer of 1,2-butylene oxide and propylene oxide; a glycerol-initiated unsaturated ester that is free of tertiary carbon atoms and quaternary carbon atoms; and an antioxidant.

The present invention relates to a process for synthesizing dispersion of ZnO nanoparticles in an oil medium. Particularly, the invention relates to a process for in-situ synthesis of dispersion of ZnO nanoparticles in oil medium. Additionally, the present invention relates to a lubricant oil composition, wherein the composition comprises a base oil, a dispersant and the dispersion of ZnO as obtained by the process of the present invention.

Disclosed is the use of a lubricating composition including at least one base oil and at least one polyalkylene glycol (PAG) produced by polymerisation or copolymerisation of alkylene oxides including between 3 and 8 carbon atoms, at least one of which being a butylene oxide, for preventing or reducing pre-ignition in an engine, preferably in a vehicle engine.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
