Abstract: The invention provides a lubricating composition comprising an oil of lubricating viscosity and an amine-functionalised additive, wherein the amine-functionalised additive is derived from an amine having at least 3 aromatic groups, at least one -NH2 functional group, and at least 2 secondary or tertiary amino groups. The invention further provides for the additive to have dispersant and/or dispersant viscosity modifying properties. The lubricating composition is suitable for lubricating an internal combustion engine.
