In the article presents an analysis of changes in the flow of failures of trucks with diesel and methane-diesel engines. As a result of analysis revealed a change in the reliability of diesel cars converted to work on compressed natural gas. This led to a change in their effective operation because of the increased amount of downtime to repair. Another reason of the decline in effective work vehicles - reduction the carrying capacity, because of the need to transportation a extra weight in the form of compressed gas cylinders. These factors directly affect the final cost of transportation of cargos and payback period of the gas equipment. As a result it was proposed to take into consideration the change in the reliability of methane-diesel vehicles in the formation of cost transportation cargos and payback calculation of gas equipment.

Keywords: Methane-diesel vehicles, gas equipment, time to failure, performance truck, the formation of cost transportation cargo, the payback period
