A grease composition includes a base oil, a thickener and at least one kind of an antioxidant selected from an amine-based antioxidant and a phenol-based antioxidant expressed by the following respective general formulas (1) and 2: ##STR00001##
The base oil contains a poly--olefin and a mineral oil. A mass ratio of poly--olefin/mineral oil is 1.25 to 9.

The disclosure relates to the use of a lubricating composition including at least one base oil and at least one organic compound for reducing, or even eliminating, knocking in the engine of vehicles, preferably motor vehicles.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

A functional fluid composition containing a fluid base stock (e.g., a phosphate ester fluid base stock) as a major component, and an erosion inhibitor mixture as a minor component. The erosion inhibitor mixture contains at least a first erosion inhibitor (e.g., a perhalometallate or perhalometalloidate salt) and a second erosion inhibitor (e.g., an alkali metal salt of perfluoroalkyl sulfonic acid). Erosion inhibition of the functional fluid composition is improved as compared to erosion inhibition achieved using singly the first erosion inhibitor or the second erosion inhibitor, as measured by one or more of ASTM D2624, ASTM D974, ASTM D130 and ASTM D6304. A method for operating and lubricating a hydraulic system by utilizing as a hydraulic fluid, the functional fluid composition. A method for identifying erosion inhibition effectiveness of the functional fluid. The functional fluids are useful as aircraft hydraulic fluids.

A lubricant additive concentrate containing (i) dispersant that is the polybutenyl succinimide reaction product of a polyamine and polybutenyl succinic anhydride (PIBSA) derived from polybutene having a number average molecular weight (M.sub.n) of from about 1300 to about 2500 daltons and a terminal vinylidene content of at least about 50% and maleic anhydride via an ene maleation process; (ii) overbased magnesium colloidal detergent having a total base number (TBN) of from about 300 to about 900 mg KOH/g; and (iii) organic friction modifier selected from hydroxyalkyl alkyl amines of C.sub.14 to C.sub.24 hydrocarbons, at least one hydroxyalkyl alkyl ether amines of C.sub.13 to C.sub.24 hydrocarbons, at least one alkyl ester amine derived from triethanol amine having a C.sub.13 to C.sub.24 hydrocarbyl substituent, at least one non-basic, fatty acid amide, or a mixture thereof; wherein the combined mass % of dispersant (i) and overbased magnesium colloidal detergent (ii) in said concentrate is from about 15 to about 50 mass %: the mass ratio of (i):(ii) is from about 1:1 to about 6:1; and the concentrate contains from about 2 to about 10 mass % of organic friction modifier (iii); the remainder of the concentrate being composed of base oil and additives other than dispersant (i), overbased magnesium colloidal detergent (ii) and organic friction modifier (iii).

The present disclosure relates to a lubricant composition including at least one base oil and at least one organic compound. The lubricant composition thus makes it possible to reduce, or even to eliminate knock in a vehicle engine, preferably a motor vehicle engine.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

A grease formulation containing a thickener and a Fischer-Tropsch derived base oil, in particular a heavy or extra heavy base oil. The use of a Fischer-Tropsch oil results in an increase in thickener concentration and in improved properties such as anti-wear and copper corrosion performance. Also provided is the use of a Fischer-Tropsch derived base oil in a grease formulation, for the purpose of improving its anti-wear and/or copper corrosion performance, and/or for reducing the concentration of an additive in the formulation.
