PURPOSE: An engine oil supply apparatus is provided to achieve a life span broadening of engine with enhanced performance while preventing an abrasion of frictional components of engine upon operation of engine after a predetermined period of stoppage. CONSTITUTION: An engine oil supply apparatus comprises an oil pump, a key box(7), an oil lamp(8),and first, second and third relay switches(RL1, RL2, RL3). The oil pump has a case having at a portion thereof an inlet and at the other portion thereof an outlet, and an inner rotor and an outer rotor engaged with each other within the case and which rotate to pump oil. The inner rotor has at a center thereof coupled with a rotary axis of a rotor of a start motor. The key box(7) has a start terminal(ST) and an ignition terminal(IG). The first switch(RL1) is turned on when a power input from the ignition terminal(IG) is input to a coil(L1) and connects a battery voltage. The second switch(RL2) is turned on when a power input from the start terminal(ST) is input to a coil(L2) and supplies an output power from the switch(RL1) to an input terminal(M) of a magnet switch(1) so as to rotate the rotor. The third switch(RL3) is always turned on and supplies the voltage input from the start terminal(ST) to an input terminal(ST) of the switch(1). The switch(RL3) is turned off when the output voltage from the switch(RL1) is input to a coil(L3). The oil pump operates prior to the ignition of engine so that each component of engine is provided with sufficient amount of engine oil.
