An environmentally-improved motor oil blend and related methods for properly lubricating components of an engine and favorably modifying a plastic response of components of the engine, the blend being free of zinc di-alkyl-di-thiophosphates (ZDDP) and free of zinc di-thiophosphate (ZDTP), comprising: a motor oil selected from the motor oil group consisting of Group I, Group II, Group III, Group IV, and Group V motor oils; a motor oil additive comprising alpha-olefins and hydroisomerized hydro-treated severe hydrocracked base oil; ZDDP omitted from the chemical constituents of the motor oil; and ZDTP omitted from the chemical constituents of the motor oil.

Disclosed is a method for preparing a low-viscosity oil including more than 50 wt % of 9-methyl-11-octyl-heneicosane. The method uses a specific metallocene catalyst and makes it possible to prepare a polyalphaolefin oil (PAO) in which the kinematic viscosity at 100° C., measured according to standard ASTM D445, ranges from 3 to 4 mm.sup.2/s.sup.−1. The oil can be used as a high-performance lubricant for lubrication in the fields of engines, gears, brakes, hydraulic fluids, coolants and greases

Disclosed are lubricating compositions and base oils for motor vehicles, specifically for engines, gearboxes, or vehicle axle assemblies. The lubricating composition contains an oil-soluble polymer that is a specific polyalkyl glycol or a specific polyalkylene glycol (PAG). Also described is use of the lubricating composition for reducing fuel consumption in a vehicle provided with an engine, an axle assembly, or a gearbox that are lubricated using the lubricating composition or the specific PAG.

The invention relates to random copolymers comprising monomers derived from conjugated dienes and alkyl (meth)acrylates, a method for manufacturing the copolymers, lubricant compositions comprising the copolymers, and the use of the copolymers as additives for lubricant compositions or as a base oil for lubricant compositions. The copolymers are favorably used for driving system lubricating oils, hydraulic oils, engine oils and industrial oil formulations.

The invention relates to a food-grade high-temperature lubricant, more particularly a high-temperature oil and a high-temperature grease, comprising the following components: a) at least one oil selected from a trimellitic ester or a mixture of different trimellitic esters, alkylaromatics, preferably an aliphatically substituted naphthalene, or estolides; b) a hydrogenated or fully hydrogenated polyisobutylene or a mixture of hydrogenated or fully hydrogenated polyisobutylene; and c) additives individually or in combination.

In the case of the high-temperature grease, a thickener is added.
