ABSTRACT:
Oil changing apparatus including an oil storage tank and a gasoline powered air compressor, both mounted on the bed of a trailer. An oil hose communicates with the storage tank, and connects into a motor being serviced. The drain plugs of motorized equipment serviced by the oil changing apparatus are provided with quick coupling connectors. The oil hose has a cooperating connector at its distal end, which connects to the modified drain plug. The drain plug connector includes a normally closed valve, to retain oil in the sump when the oil hose is not attached thereto. A first air hose enables the air compressor to draw air from the storage tank in the oil drain mode. Oil is removed from the serviced motor by suction. In the purge mode, accumulated old oil is rapidly purged from the tank. A second air hose conducts pressurized air from the compressor to the storage tank, which forces oil from the storage tank when emptying the same. An accessory enables purging an oil filter cartridge with the novel apparatus. The accessory comprises a conduit having a pointed end, a quick coupling connector for attachment to the oil hose, and an integral slide hammer for assisting in piercing the cartridge. The resultant oil changer is mobile, of minimal complexity and cost, built from readily available parts and materials, and is not reliant upon availability of electrical power or sources of compressed air or vacuum.
