Abstract: An apparatus for remotely monitoring the level of lubricant in a sump of an internal combustion engine on a vehicle and remotely transferring lubricant from the engine sump including a lubricant tank mounted on the vehicle external to the vehicle's engine. The lubricant tank and the engine may each contain a quantity of gas above the respective lubricant levels in the tank and the sump with the pressure of gas contained in the lubricant tank being regulated relative to the pressure of gas contained in the engine such that the level of lubricant in the tank is indicative of and varies along with the level of lubricant in the engine sump. The apparatus may include an equalization connection between the sump and the tank and an evacuation connection to the tank for transferring lubricant from the tank. The tank may include a plurality of internal chambers situated for lubricant to flow between them to prevent lubricant from being drawn out of the sump below a lubricant low-level limit of the sump.
