    Abstract: A novel polyamide capable of improving the pour point, dispersancy and detergency characteristics of a lubricating oil comprises a polyamide of a mixture of secondary and tertiary monocarboxylic acids having 19 to 31 carbon atoms in the molecule and a polyalkylene polyamine containing about 2 to about 6 alkylene units, there being from 2 to 4 carbon atoms in each alkylene group, said polyamide containing about 1 to about 3 amine groups in addition to amide groups.
