ABSTRACT OF THE DISCLOSURE It is known that the hydraulic oil in machinery must be changed at intervals from about 500 to 1000 operating hours. Generally, the hydraulic oil change occurs at the work site due to the prohibitive cost of returning the machinery to a machine shop. The used oil is usually discarded and replaced with fresh oil. However, as hydraulic oil is not subject to destructive operating conditions the practice is wasteful, and presents an environmental hazzard. In order to overcome this draw- back the present invention provides a method of treating spent hydraulic and transmission oil removed from a mobile machine coprising drawing the oil from said machine in its workplace into a trough disposed below the machine and thereafter filtering the oil through a filter under a particular and predetermined pressure, into a vessel, said trough, filter and vessel being separate from the machine.
