Organic esters, to be employed to make up lubricating compositions are disclosed, said esters being the products of the reaction between a diol and a triol, on the one hand, and a mixture of saturated monocarboxylic acids, on the other hand. The ratios of the diol to the triol (molarly) and the structure and number of carbon atoms of the saturated monocarboxylic acids are critical. Critical values are given, as well as examples of practical use; the viscosity and viscosity index properties of the novel esters out do those of the conventional esters to a degree.
