An oil dispenser for internal combustion engines having a crankcase includes an oil-containing, airtight reservoir disposed at a vertical location above the crankcase. A conduit connects the reservoir and the crankcase in order to establish fluid communication between the reservoir and the crankcase. The conduit has a lower end disposed in the crankcase at a level at which oil is desired to be maintained in the crankcase. A solenoid-activated valve is disposed at the lower end of the conduit to selectively permit or prevent the flow of oil through the conduit. The solenoid-activated valve includes a cup-like member which surrounds and is fitted against the lower end of the conduit upon valve closure. A control means is connected to the solenoid-activated valve for opening the solenoid-activated valve only after the engine has ceased operation and after a predetermined period of time has elapsed.
