The invention discloses a lubricating grease with thixotropy and a preparation method thereof. The lubricating grease comprises a polyurea/high base number calcium sulfonate composite thickener, colloidally dispersed calcium carbonate solid particles in the form of calcite, a calcium borate or calcium borate composite, and a calcium soap of fatty acid having 12 to 24 carbon atoms. The above components are uniformly dispersed in an oil phase medium. The content of high base number calcium sulfonate in the lubricating grease is less than 22 wt %.

The present invention relates to the use of organometallic salt compositions as lubricant additives and/or lubricant additive compositions to alleviate the formation of white etching cracks (WEC).

The instant disclosure generally relates to lubricating compositions having an oil of lubricating viscosity, a mixture of boron-containing and boron-free dispersants, an overbased magnesium-based detergent, an overbased calcium-based detergent, a molybdenum-containing material, and, optionally, other performance additives. The instant lubricating compositions may improve one or more of cleanliness, TBN retention, fuel economy and low-speed preignition (“LSPI”).

Traction fluids comprising Formula I, II, III, IV, V, VI, VII or a mixture thereof in combination with a base stock, a viscosity modifier, an anti-foaming agent, and an additive package.

A method for combined production of renewable paraffinic products is disclosed, wherein the method includes providing a renewable paraffinic feed, and fractionating the renewable paraffinic feed into two fractions. Within the two fractions, a lighter fraction fulfils a specification for an aviation fuel component, and a heavier fraction fulfils a specification for an electrotechnical fluid component.

The present invention relates to the use, for cooling and lubricating a propulsion system of an electric or hybrid vehicle, of a composition comprising: (i) at least one base oil; and (ii) at least one diester of formula R.sup.a—C(O)—O—([C((R).sub.2)].sub.n—O).sub.s—C(O)—R.sup.b (I), different than the base oil (i). The invention also relates to a method of cooling and lubricating a propulsion system of an electric or hybrid vehicle comprising at least one step of bringing at least one mechanical component of said system into contact with a composition as defined above.

A product resulting from the reaction of at least: a hydroxybenzoic acid, optionally substituted by a hydrocarbyl group, or an alkali and/or alkaline earth metal salt thereof, a boron compound, a polyalkylamine component selected from triamine and tetramine compounds. Also, a lubricant composition including this product. Use of this product as a lubricant for two-stroke marine engines and four-stroke marine engines, more preferably two-stroke marine engines.

A continuous process for converting waste plastic into recycle for polypropylene polymerization is provided. The process integrates refinery operations to provide an effective and efficient recycle process. The process comprises selecting waste plastics containing polyethylene and polypropylene and then passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a refinery FCC unit, from which is recovered a liquid petroleum gas C.sub.3 olefin/paraffin mixture. The C.sub.3 paraffins and C.sub.3 olefins are separated into different fractions with a propane/propylene splitter. The C.sub.3 olefin fraction is passed to a propylene polymerization reactor. The C.sub.3 paraffin fraction is optionally passed to a dehydrogenation unit to produce additional propylene and then the resulting C.sub.3 olefin is passed to a propylene polymerization reactor. The heavy fraction of pyrolyzed oil is passed to an isomerization dewaxing unit to produce a lubricating base oil.

The present disclosure relates generally to antioxidants. More particularly, the present disclosure relates to lubricating compositions comprising an antioxidant.

Low molecular weight polyalkyl acrylate polymers can be used as high viscosity base fluids. A corresponding method can be used for their preparation. Lubricant compositions may contain such low molecular weight polyalkyl acrylate polymers and the compositions may be used as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or hydraulic oils.
