Abstract

Abstract A disposable oil draining apparatus for a vehicle comprises a normally-closed valve having a threaded end which replaces the normal drain plug in the vehicle oil pan. A valve actuator is releasably connected to the valve by way of a spring-loaded latch and is in communication with a disposable plastic bag which serves as a drain reservoir.
