Abstract: The invention provides a grease composition for a ball joint which has a low friction coefficient under a load from normal temperatures to high temperatures, a small difference between static friction and dynamic friction, and little change in the friction coefficient even after repeated operation. TO this end, the invention provides a grease composition for a ball joint comprising: (i) a polyisoprene rubber and/or (ii) a polyisoprene rubber viscous material; a specific aliphatic amide and/or a specific aliphatic bisamide; and a specific urea compound.

Abstract: A grease composition containing a urea compound as a thickener, a base oil, an alkaline earth metal salicylate and/or an alkaline earth metal phenate as a first additive constituent, a metal soap, being a stearic acid metal salt, as a second additive constituent, and a calcium sulphonate and/or a zinc naphthenate as a third additive constituent.

Abstract: A grease composition with high wear resistance, comprising a base oil, a thickener and a poly(meth)acrylate derivative.

Abstract: The present invention provides a lubricating oil composition comprising a base oil made of synthetic oil and/or mineral oil, admixed with an antioxidant and a polymethacrylate having a phosphate ester added to a terminal position. In a further aspect the present invention provides the use of the lubricating oil composition as a transmission oil, in particular as an automatic transmission oil.

Abstract: Lubricating oil composition containing components (A)-(C) in a base oil is provided. The components (A)-(C) are (A) one or more metal detergents selected from optionally substituted divalent metal phenates, optionally substituted divalent metal salts of salicylic acid and optionally substituted divalent metal salts of sulphonic acid; (B) one or more zinc dialkyl dithiophosphates; and (C) one or more compounds selected from (i) one or more fatty acid esters, and/or (ii) one or more further phosphorus compounds.
