PURPOSE: An engine lubrication device is provided to lengthen the life of an engine by quickly lowering the viscosity of an engine oil when the viscosity is increased by the cooling of the engine. CONSTITUTION: In an engine lubrication device for a vehicle, a three-way valve(50) is installed in a return pipe which is an oil passage returning the oil to an oil pan, and selectively opens/closes an oil pump and the oil pan. The three-way valve is operated by on/off of an electronic valve(40), and recirculates the returned oil without feeding the returned oil to the oil pan in initial start. The electronic valve is controlled by an ECU(20) receiving the temperature of the oil.
