Abstract: Novel dispersant mixtures are provided, having improved lubricating oil performance characteristics, comprising nitrogen or ester containing dispersants selected from the group consisting of oil soluble salts, amides, imides, oxazoline and esters or mixtures thereof, wherein a first dispersant comprises a long chain hydrocarbon substituted mono- and dicarboxylic acid or their anhydrides derived from polymers of C.sub.2 to C.sub.10 monoolefins wherein the polymer has a number average molecular weight of at least about 1300 and wherein the second dispersant component is derived from such polymers having a number average molecular weight of from about 700 to 1150. The relatively high molecular weight dispersant is provided with from about 1.05 to 1.25 moles per mole of polyolefin of an alpha or beta unsaturated C.sub.4 to C.sub.10 dicarboxylic acid or anhydride or ester thereof. The relatively lower molecular weight dispersant is provided with from about 1.2 to 2.0 moles per mole of polyolefin of an alpha or beta unsaturated C.sub.4 to C.sub.10 dicarboxylic acid, anhydride or ester thereof. It has been found that mixtures of such high molecular weight-low functionality dispersants and low molecular weight-high functionality dispersants provides a dispersant, suitable for use in oleaginous materials such as lubricating oils, which provide surprisingly improved engine performance properties.

Abstract: A fuel composition for internal combustion engines, and more particularly, a fuel composition for internal combustion engines containing less than about 0.5 gram of lead per liter of fuel is described. The fuel composition comprises a major amount of a liquid hydrocarbon fuel and a minor, property improving amount of(A) at least one hydrocarbon-soluble alkali or alkaline earth metal-containing composition, and(B) at least one hydrocarbon-soluble ashless dispersant.When a mixture of the metal-containing composition (A) and the ashless dispersant (B) are incorporated into gasolines containing less than about 0.5 gram of lead per liter of fuel, the treated fuel exhibits improved stability and water tolerance, and when the unleaded or low lead-containing fuels of the present invention are utilized in internal combustion engines, there is a significant reduction in valve seat recession. Methods of reducing valve seat recession in internal combustion engines utilizing lead free or low lead-containing fuels also are described.

Abstract: Hydroxy aromatic compositions containing (a) a hydroxyl group bonded directly to a carbon of an aromatic nucleus, (b) a hydrocarbon-based substituent of at least about 50 aliphatic carbon atoms bonded directly to a carbon atom of an aromatic nucleus, (c) at least one methylol or lower hydrocarbyl substituted methylol substituent bonded directly to a carbon atom of an aromatic nucleus, and not having any alkylene linkages between carbon atoms of two aromatic nuclei are useful as additives for normally liquid fuels and lubricating oils. These hydroxy aromatic compositions are also useful as intermediates for preparing other additives for fuels and lubricants. Typical hydroxy aromatic compositions of the present invention are formed by reaction of formaldehyde with an alkenyl- or alkyl-substituted phenol wherein the alkyl or alkenyl substituent contains an average of about 50 carbon atoms.
