In this article, the results of studying C9-C17 carbon fatty acid amides as lubricating-dispersing additives for diesel fuel are presented. Additionally, the determination of lubricating-dispersing properties was carried out by sedimentation of the prepared stabilizing agent system based on colloidal graphite of the C-1 grade at a concentration of 1.0% by mass, resulting in a change in optical density. The determination of antioxidant efficiency was based on the photometric method, where, under experimental conditions, a change in optical density in the oxidation process was detected.
