Patent ID: 7534747

Claim:
A composition comprising one or more lubricant additives in a form of a gel wherein the gel is represented by the formula A+B+C wherein the components A and B interact to form a gel and component C is contained within the gel; wherein the gel is semi-solid; wherein the weight ratio of component A to component B is from about 1:4 to about 1:2; wherein A is selected from the group consisting of antioxidants, dispersants, succinics, maleic anhydride styrene copolymers, maleated ethylene diene monomer copolymers, surfactants, emulsifiers, functionalized derivatives of such components and combinations thereof; wherein B is selected from the group consisting of dispersants, detergents, overbased detergents, carbon black, silica, alumina, titania, magnesium oxide, calcium carbonate, lime, clay, zeolites and combinations thereof; and wherein C is selected from the group consisting of antioxidants, extreme pressure agents, wear reduction agents, viscosity index improvers, anti-foaming agents and combinations thereof; and wherein the gel dissolves into a lubricating oil of a lubricating oil engine over time; and wherein the gel components are controlled released and used in an application selected from the group consisting of decreasing the amount of soot in the lubricating oil of an engine, decreasing the amount of emissions in the engine exhaust and combinations thereof; wherein the composition has a tan delta value of ≦0.75.
