Abstract High-quality diesel fuel is the guarantee of work of an internal combustion engine. Low ambient temperature has an influence on the physical and chemical properties of diesel fuel. It becomes a reason for failure of details of a high pressure fuel pump system. This issue is more acute in the Republic of Sakha (Yakutia) where the surrounding air temperature can reach up to -60C and where the essential goods are delivered to the regions of the Far North by winter roads. The article illustrates the results of experimental study of the quality of arctic diesel fuel taken from different filling stations of the Republic of Sakha (Yakutia). It also suggests a way of increase of fuel efficiency for equipment operated in the North. The article also presents a mathematical model of fuel cost during winter time. The main operational properties of arctic diesel fuel are studied. The work was carried out in the laboratory of “General, analytical and physical chemistry” department. The samples of diesel fuel were divided into three categories according to their geographic locations: central, northern and riverside. Three samples of arctic diesel fuel from different filling stations were taken in each of the regions. The study revealed that the chosen main properties of diesel fuel, such as: density, viscosity, fractional structure and low-temperature properties differ from standard values.
