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 present disclosure relates to lubricating oil compositions, and in particular, lubricating oil compositions for slideway applications, additive compositions for the slideway lubricants, and methods of lubricating a machine part, such as a slideway with the lubricating oil compositions. In one aspect, the lubricating oil compositions have a composition that provides both good friction performance and good separability from metal working fluids at the same time.

Implementations of wax ester compositions may include: a product of transesterifying oleyl oleate, stearyl stearate, and behenyl behenate using one of a chemical or an enzyme catalyst. The ratio of the oleyl oleate to stearyl stearate to behenyl behenate in the mixture prior to transesterification is one of 65%/23%/12%, 56%/29%/15%, or 36%/34%/30%, respectively, measured by weight. The product may demonstrate a substantially equivalent physical property to a physical property of a transesterified wax ester composition including a jojoba ester.

There is provided a petrolatum substitute. The petrolatum substitute preparation comprises 1-20 wt % of at least one oil thickening agent, 7-40 wt % of at least one structuring agent, 0.5-10 wt % of at least one phytosterol or ester thereof, and 30-92 wt % of at least one emollient, wherein the preparation has a melting point of 35? C. or more. The petrolatum substitute preparation can be used in essentially all applications where petrolatum is used today. The substitute can be made renewable and the use of over-exploited natural products is minimized. The preparation is less irritant and has excellent moisture barrier properties when applied to human skin. Further it is less energy consuming to manufacture.

A lubricating composition includes: from 0.1% to 10% by weight of a first organic acid including a fatty acid containing from 4 carbon atoms to 18 carbon atoms; from 1% to 10% by weight of a fatty amine containing from 10 carbon atoms to 26 carbon atoms; from 0.1% to 5% by weight of an acidity corrector; up to 10% by weight of a dispersant; up to 10% by weight of a second organic acid; up to 10% by weight of an organic solvent; and from 50% to 98.8% by weight of water.

The present invention provides a lubricant composition which can be washed off cold and the use thereof for application to a metal strip as anti-corrosion, wash and/or forming lubricant. The composition is 50 to 90 wt % base fluid, 3 to 15 wt % sulfonate-based corrosion inhibitor, 1 to 20 wt % ester component, 0.5 to 3 wt % phosphorus source component or 1 to 10 wt % sulfur source component as high-pressure/anti-wear additive, 1 to 15 wt % emulsifier, 0.05 to 1 wt % carboxylic acid component, 0.05 to 1 wt % aminic and/or phenolic antioxidant, 0.5 to 5 wt % wax and/or thickener component, based in each case on the total weight of the composition. Further disclosed is a dry lubricant composition which can be washed off cold.

There is provided a petrolatum substitute. The petrolatum substitute preparation comprises 1-20 wt % of at least one oil thickening agent, 7-40 wt % of at least one structuring agent, 0.5-10 wt % of at least one phytosterol or ester thereof, and 30-92 wt % of at least one emollient, wherein the preparation has a melting point of 35? C. or more. The petrolatum substitute preparation can be used in essentially all applications where petrolatum is used today. The substitute can be made renewable and the use of over-exploited natural products is minimized. The preparation is less irritant and has excellent moisture barrier properties when applied to human skin. Further it is less energy consuming to manufacture.

Fuel and lubricant compositions are provided that contain a primary low-speed pre-ignition (LSPI)-reducing additive comprising (i) an amino additive, (ii) an amine additive, (iii) a triazole additive, (iv) a benzamidinium additive, (v) a benzoxazole additive, or (vi) a NCX motif additive. Methods for preventing or reducing low speed pre-ignition events in spark-ignited engines using these compositions are also provided.
