The present invention provides a multiple function dispersant viscosity index improver, a method of making the multiple function dispersant viscosity index improver, and a lubricating oil comprising the multiple function dispersant viscosity index improver. The multiple function dispersant viscosity index improver comprises two different functional groups, each directly grafted to a polymer backbone having graftable sites. The first functional group comprises the reaction product of an acylating agent and a first amine, the first amine comprising an aromatic primary amine, and the second functional group comprises the reaction product of an acylating agent and a second amine, the second amine comprising an aliphatic primary amine. The first functional group provides the dispersant viscosity index improver with soot handling performance attributes and the second functional group provides the dispersant viscosity index improver with sludge and varnish control performance attributes.


A lubricating composition comprising a base oil of lubricating viscosity and one or more lubricant additives, wherein the base oil comprises or consists of a base stock which comprises or consists of at least one isoprenoid compound comprising: (i) one or two oxygen-containing moieties independently selected from ether and ester moieties; (ii) a first acyclic isoprenoid moiety containing 1 to 5 isoprenyl units; and (iii) optionally, a second acyclic isoprenoid moiety containing 1 to 5 isoprenyl units with the proviso that at least one isoprenoid moiety contains 3 to 5 isoprenyl units where the isoprenoid compound contains a single ether moiety.


The use as an anti-wear additive and/or friction modifier in a non-aqueous lubricant composition and/or in a fuel composition of at least one long chain fatty acid ester of a hydroxy carboxylic acid in which the long chain fatty acid has at least 4 carbon atoms and the ester is an oil-soluble ester of a mono- or poly-hydroxy carboxylic acid having 1 to 4 groups which are independently carboxylic acid groups or lower hydrocarbyl esters thereof and in which, when the hydroxy carboxylic acid is a mono-hydroxy carboxylic acid, the ester has a long chain fatty acid ester moiety of the hydroxy group of the hydroxy carboxylic acid and, when the hydroxy carboxylic acid is a poly-hydroxy carboxylic acid, the ester has independently long chain fatty acid ester moieties of one or two of the hydroxy groups of the poly-hydroxy carboxylic acid. Also, a non-aqueous lubricant composition and a fuel composition for an internal combustion engine which comprises at least one of said long chain fatty acid esters.
