Abstract: An apparatus for enhancing the efficacy of an engine oil change includes an oil filter adapter positioned in sandwiched relation between an oil filter housing of an engine and an oil filter. A plurality of outlets formed in the oil filter adapter is in fluid communication with the oil filter inlet and with the oil filter housing. An air inlet formed in the oil filter adapter is in fluid communication with a source of compressed air so that when compressed air is admitted into the air inlet, the compressed air flows through the oil filter housing opening and into the oil pan. The compressed air dislodges residue from an oil pump screen when the engine is not running, dislodges residue from interior walls of the oil pan after the engine has been operated and shut down, and purges dirty oil and residue when dirty oil is drained from the oil pan.

Abstract: A method of cleaning the transmission system of a vehicle includes the steps of starting an engine of the vehicle and bringing it to normal operating temperature. A predetermined amount of a transmission cleaner is charged into the transmission and the vehicle is driven for a predetermined distance. The gears are changed at preselected times while driving so that all gears of the transmission are used equally. The engine is then shut down and transmission fluid is purged from the transmission fluid pan by submerging a trailing end of a first hose into the transmission fluid. A leading end of the first hose is connected into fluid communication with an inlet of a remote charging tank and an outlet of the remote charging tank is connected through a switch to a source of negative pressure. The switch is set to cause the transmission fluid to flow into a transmission fluid waste tank disposed between the outlet and the source of negative pressure.

Abstract: An engine cleaning apparatus and process for removing contamination from internal oil passages, internal water passages, internal air/fuel passages, and internal exhaust system passages of an internal combustion engine comprising a pump working in communication with a fluid supply line and a fluid return line to pump and vacuum a solvent fluid through the passages of the engine.
