Improved lubricating oil for high pressure polyethylene compressors contains white mineral oil or synthetic oil blended with oleic acid in an amount less than 15 wt %, and preferably 0.5-5 wt. %, an EP additive such as a phosphorus containing compound made by phosphating mono or diglycerides derived from vegetable oils and having one or two neutralized acid sites, and no more than 1.0 wt. %, and preferably no more than 0.1 wt. %, of an antioxidant of the phenolic type, and a polybutene viscosity builder in the amount necessary to achieve the expected or desired viscosity. The lubricating compressor oil according to the invention has improved lubricity and gives wear protection over the whole range of lubricating regimes including EP conditions.

Disclosed are hydrophobic compositions useful for filling the voids within jacketed optical fiber cables. The compositions include about 85 to 95 parts by weight of mineral oil, 5 to 15 parts by weight of a (styrene)-(ethylene/propylene) diblock copolymer having a styrene: (ethylene/propylene) ratio of 37.5:62.5 to 27.5:72.5 and a specific gravity of about 0.90 to 0.95, optional antioxidant, and optional metal deactivator.

An oil particularly suited for equipment having copper containing alloy elements, is compounded from about 20 to 99.75% by weight of natural or synthetic oil, and about 0.25 to 30% by weight of an acid forming friction modifier, particularly, a fully esterified compound, such as glycerol trioleate (GTO). The oil evidences a marked improvement in frictional behavior and wear protection, especially regarding the corrosive wear of Cu based alloys. The oil containing glycerol trioleate does not release oleic acid unless and until boundary conditions are present, thereby on one hand effectively lubricating under boundary conditions, while on the other hand minimizing the presence of oleic acid and thereby reducing chemical wear.
