One of important features of development of modern society is special attention world the public to problems of rationality and efficiency of use of the existing energy resources, universal implementation of technologies of energy saving and search of renewable energy resources. Gradual depletion of world reserves of oil, increase in prices for traditional motor fuels, adverse ecological situation and other factors prove the relevance of more urgent use of the available resources and works promoting development of this direction. Deterioration in a global ecological environment requires adoption of more strict requirements imposed to the fuel used in an agro-industrial complex. According to the principle of cost accounting, each entity can rely only upon itself and consume only the resources it has. It is known that fuel costs constitute a considerable part in an expense structure of agricultural enterprises. In this case, the reduction in fuel consumption can be achieved through improved processes of fuel mixing and fuel processing (fuel dearomatization, ultrasonic treatment, magnetic, electrostatic and electromagnetic processing). Bench tests of a diesel engine equipped with an experimental device for ultrasonic treatment, showed good results, confirming the relevance of the use of such devices. Devices for processing are compact enough and consume little energy, while having a sufficiently high coefficient of performance. Having small size and relative simplicity of design that does not cause complex technical issues in production, these devices can be used on virtually any type of equipment that is used for the solution of agricultural problems. The purpose of this article is to evaluate the economy of the diesel fuel when ultrasonic treatment on the example of the motor transportation enterprise
