Abstract: A tube is inserted to a predetermined depth into the dip stick orifice of an internal combustion engine of a vehicle and connected to a small pump to initiate oil circulation in a line between the dip stick orifice and the oil filler tube. A pressure sensitive switch is inserted in this line and held in a normally open position while sufficient pressure is being sensed. When the oil level of the engine falls below the tube, the oil pressure sensed by the oil sensor switch drops and the contacts close lighting an indicator light disposed on the instrument panel of the vehicle. An oil reservoir is positioned above the engine and is connected to the oil filler tube. A valve is disposed between the reservoir and the oil filler tube of the engine and can be operated through a remote control from inside the vehicle. When the oil warning light is actuated, the vehicle operator can actuate the valve to allow a predetermined amount of oil to flow into the engine.
