Abstract

Abstract Apparatus for the suction of oil from an oil sump of a motor vehicle through the dipstick opening, comprises a wheeled frame which supports an oil storage container and an electric pump having an oil outlet duct leading to the oil storage container. Three dipstick suction probes of different sizes are connected to the pump via valve means for actuating each said probe independently of the other probes.
