20080223330 | ADDITIVES AND LUBRICANT FORMULATIONS FOR IMPROVED ANTIWEAR PROPERTIES - A lubricated surface, a method for reducing wear between moving parts, and lubricants, and lubricant additive concentrates containing a wear reducing agent. The lubricated surface contains a base oil of lubricating viscosity, a hydrocarbon soluble titanium compound, a metal-free friction modifier and an amount of at least one hydrocarbon soluble magnesium compound effective to provide a reduction in surface wear greater than a reduction surface wear for a lubricant composition devoid of the titanium compound, metal-free friction modifier, and magnesium compound. The lubricant composition contains no more than about 800 ppm phosphorus and is devoid of calcium detergents and organic molybdenum compound. | 09-18-2008 |
20080236538 | LUBRICATING OIL COMPOSITION FOR IMPROVED OXIDATION, VISCOSITY INCREASE, OIL CONSUMPTION, AND PISTON DEPOSIT CONTROL - An engine oil lubricant composition having improved control of oxidation viscosity, and piston deposits is provided. The composition further exhibits performance on the ASTM Sequence IIIG Test of about 90% or less kinematic viscosity increase at 40° C. and about 5.5 or more merits average weighted piston deposits. The composition meets or exceeds the standards of both the ILSAC GF-4 and the General Motors GM4718M specifications. | 10-02-2008 |
20090156445 | LUBRICANT COMPOSITION SUITABLE FOR ENGINES FUELED BY ALTERNATE FUELS - A lubricant composition suitable for use in engines fueled by gasoline or biorenewable fuels or both, comprising an oil of lubricating viscosity and a dispersant system is disclosed herein. Also disclosed is an emulsion composition comprising a biorenewable fuel, an oil of lubricant viscosity, and a dispersant system. A method of reducing aqueous separation in an emulsion composition is also disclosed. | 06-18-2009 |
20100279902 | LUBRICANT FORMULATIONS AND METHODS - The embodiments described herein relate to particular formulations and methods that provide reduced engine deposits. The lubricant composition includes a base oil having a NOACK volatility of from about 5 to about 15 and a zinc dialkyl dithio phosphate composition. The zinc dialkyl dithio phosphate composition has at least about 65 mole percent of zinc dialkyl dithio phosphate compounds derived from all primary alcohols, wherein the zinc dialkyl dithio phosphate composition has greater than about 40 mole percent zinc dialkyl dithio phosphate compounds having alkoxy moieties derived from alcohols having four carbon atoms. | 11-04-2010 |
20100317552 | LUBRICATING METHOD AND COMPOSITION FOR REDUCING ENGINE DEPOSITS - A lubricant composition, lubricant concentrate and method for reducing engine deposits. The composition and method include a base oil of lubricating viscosity; an organo-molybdenum compound; a deposition reducing amount of a reaction product of an alkyl-substituted dicarboxylic acid compound selected from the group consisting of alkyl-substituted dicarboxylic acids, alkyl-substituted dicarboxylic acid anhydrides, and mixtures thereof, and a basic salt of aminoguanidine, in an amount sufficient to provide a product rich in alkyl bis-3-amino-1,2,4-triazole; and optionally a phenate detergent. The lubricant composition and method provide engine deposits that are less than an amount of engine deposits in the absence of component (c) and/or optional component (d). | 12-16-2010 |
