- A container to hold engine lubrication oil. In a wet-sump oil system, all the oil is held in the crankcase. However, in the dry-sump lubrication system, the oil is stored in a tank external to the engine. The dry-sump system is used to make the engine dimension smaller or for engines used in inverted flight.
