Provided are polyalkoxylates that are prepared by alkoxylating polytetrahydrofurane with butylene oxide for use in lubricant compositions and/or for reducing friction in a driveline.

A composition includes molybdenum disulfide, epoxy binder, and 0.01 to 3 wt % lead. The composition is useful, for example, as dry film lubricant.

The present disclosure relates to methods, systems, hydraulic fluids and additives for reducing the rate of surface current degradation for components in a hydraulic system, wherein the hydraulic system is exposed to phosphate-ester-based hydraulic fluid.

The present invention relates to a lubricant composition, in particular for a gas or steam turbine, comprising: at least one base oil; at least one phenylnaphthylamine (PAN) compound, preferably alkylphenyl--naphthylamine (APAN) compound; at least one diphenylamine (DPA) compound, preferably dialkyl-diphenylamine compound; and at least one phosphite ester compound, preferably triaryl phosphite ester compound; in which the ratio by weight between said diphenylamine compound(s) and said phosphite ester compound(s) is strictly greater than 1.0.
