A dynamic engine oil pickup system is disclosed. The dynamic engine oil pickup system includes a scavenge pump and a pickup tube assembly in fluid communication with the scavenge pump. The pickup tube assembly includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations and a flow control operable to control a flow of engine oil between the at least two different oil pickup locations and the scavenge pump. The flow control includes a suction valve, and movement of the suction valve is controlled by selectively applying a high pressure oil to a head of the suction valve.
