The invention provides a method of providing antiwear performance to a driveline device, wherein the driveline device includes a manual transmission that may or may not contain a synchronizer system, or an axle,
the method comprising supplying to the driveline device a lubricating composition comprising an oil of lubricating viscosity and a product obtained/obtainable by reacting:
(i) a hydroxy-containing carboxylic compound, a phosphorylating agent, or reactive equivalents thereof, and optionally an alcohol,
wherein the hydroxy-containing carboxylic compound is derived from a partially esterified polyol, or mixtures thereof; and
wherein the phosphorylating agent, or reactive equivalents thereof is POC13, P2 0s, P4 0i0 or polyphosphoric acid, and
(ii) reacting the product of (i) with a branched secondary or tertiary monoamine, or mixtures thereof;
wherein the product is present at 0.01 to 5 wt % or 0.05 wt % to 2 wt %, or 0.1 wt % to 1 wt %, or 0.2 wt % to 0.5 wt % of the lubricating composition.
