City Transformer, hardware oil change in Tveria.
Hardware oil change is carried out at service stations. To remove waste oil from the engine or gearbox, an oil change unit is used that pumps oil out of a car warmed up to operating temperature by creating a pressure difference between the reservoirs of the car and the receiving unit. At the same time, the pumped-out liquids are replaced with fresh ones, using a pump.
