An auxiliary lubricant comprising a composition, the comprising intermediate molecular weight surfactant-functionalized nanoparticles dispersed in a base oil.

An oil composition comprising a first component having pendant groups and a second component but free of a third component and process for making such oil composition, where a single molecule of the third component can form large shearable stable complex structure with two molecules of the first component via van der Waals force between pendant groups and the terminal carbon chains, and a single molecule of the second component is capable of adjoining no more than one molecule of the first type. The oil composition has high shear stability making it suitable for use in lubricants subject to repeated high shear stress events.

A lubricant composition for high compression spark ignition engines that contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A method for preventing or reducing engine knock and pre-ignition in an engine lubricated with a formulated oil. The formulated oil has a composition including at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A fuel composition for high compression spark ignition engines that contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A method for preventing or reducing engine knock and pre-ignition in an engine by using a fuel additive composition in a gasoline fuel composition. The fuel additive composition contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). The lubricating oils of this disclosure are useful as passenger vehicle engine oil (PVEO) products.

A lubricant composition of 40 to 95% of an oil having a kinematic viscosity at 100 C. of 3 to 7.5; 0.3 to 2% of an amine salt of a phosphorus compound obtained by reacting phosphorus pentasulfide with one or more alcohols having 4 to about 13, or 4 to 8, or 6, carbon atoms, with an alkylene oxide, and further with phosphorus pentoxide, and salting the resulting material with one or more amines having 2 to 20 or 12 to 24 carbon atoms; and an active-sulfur containing agent in an amount to provide 0.5 to 7% sulfur to the composition provides good wear protection to gears at a relatively low viscosity of the composition.
