Abstract: An oil filter drainage box having a plurality of support members for holding spent oil filters. The drainage box comprises a container having four side walls, a lid and a base member. The spent oil filters are placed on the support member and the residual oil in the filters drains out due to gravitational forces. The base member is inclined slightly to allow the oil to collect in a reservoir which is situated within the base member. There is a plurality of support posts extending upwardly perpendicular to the base member for engaging the spent oil filters. The lid provides a watertight seal which prevents the oil from leaving the box and damaging the environment. The reservoir is provided with a valve assembly. The valve assembly has a coupling which is attached to the reservoir, a valve, and a hose. The hose is attached to an oil vacuuming unit, which is preferably mobile and carries a complement of storage tanks and air compressor/vacuuming units.
