A drain valve and drain system which includes a gravity drain valve which can be readily installed with common tools, a hose connected to the valve and a drained fluid reservoir. Valve actuation is accomplished by a common tool such as a screwdriver or Allen wrench, in the slotted end of a valve stem which allows a recessed actuator, precluding accidental opening or stem damage. Angled side discharge or valve allows complete gravity drainage and manual installation of valve without simple tools. Side discharge and recessed actuator results in a valve with very compact external dimensions only slightly larger than a drain plug. Appliation of drainage system to crankcase oil drain, results in a clean and reliable method of changing oil without tools, funnels, rags, and pans, without significantly impacting road clearance or full drainage capability.
