Abstract
A method and a kit for oil removal or injection into the oil pan of a vehicle, marine or aircraft engine. A modified dip stick tube extends to the bottom of the oil pan has at least one or more openings at its bottom end to allow oil to enter or exit. The top has an air-tight seal that can be attached to a flexible tube that can be run to a peristaltic pump. The pump can have an exit tube that runs into an oil recovery receptacle. After draining, the oil, the tube can be valved or physically relocated to a fresh oil source. The direction of rotation of the pump can be reversed to fill the oil pan with fresh oil. An electric control can run the pump in both a forward and reverse direction typically from a vehicle battery voltage source.
