ABSTRACT:
The disclosure relates to a system for removing lubricating oil from an internal combustion engine oil pan or sump through an associated dipstick. The lubricating oil removing system includes an electric pump which is connected by two wires and associated alligator clamps to a D.C. battery of the associated automobile and to an electric switch of an electric motor of a direct current pump. The pump includes two tubes, a first of which is introduced into the engine oil pan or sump through the dipstick tube and a second of which conducts oil to a reservoir, such as a collection tank, container or jug. The second tube includes a flexible hand siphon vacuum pump downstream of the electric pump whereby the flexible hand siphon vacuum pump can be repetitively pumped to suction lubricating oil from the engine sump/oil pan into the suction end of the electrically driven pump to prime the latter prior to closing the switch to drive the electric pump and draw the lubricating oil from the engine oil pan/sump through the first tube and deliver the same through the second tube to an appropriate oil collection pan or container.
