Abstract: A residual oil drainage system for use in replacement of the oil filter of an internal combustion engine is disclosed. The drainage system may include first and second drainage conduits disposed in the oil pan of the engine. The drainage conduits may be fluidly interconnected and coupled to portions of the oil inlet and outlet flow conduits which normally convey oil to and from the oil filter. A flow control device is movable to either open or close the drainage flowpath in the system. In use with an open flowpath and engine off, residual oil captured by the first and second drainage conduits flows through the drainage system and is returned to the oil reservoir in the oil pan via gravity. In one configuration, the drainage conduits are formed internally and directly within the body of the structure of the oil pan.
