A method for separating a lubrication oil from a waste fluid includes separating water from the waste fluid by heating the waste fluid while sealed in a first vacuum chamber to a first temperature and first pressure. Fuel oil is separated from a fluid received from the first vacuum chamber by heating the fluid while sealed in a second vacuum chamber to a second temperature that is higher than the first temperature and at a second pressure. Finally, the lubrication oil is separated from a fluid received from the second vacuum chamber by heating the fluid received from the second vacuum chamber while sealed in a third vacuum chamber to a third temperature that is higher than the second temperature and at a third pressure.
