An oil flow control system has a flow control device and an oil accumulator controller. The flow control device includes a body, a passage extending through the body, and a flow control portion configured for selectively controlling flow through the passage. The oil accumulator controller is coupled to an actuation portion of the flow control device and is configured for receiving an engine oil pressure indicating signal from an engine oil pressure sensor, for receiving Minimum Engine Lubrication Oil Pressure (MELOP) threshold computing information for an engine comprising the engine oil pressure sensor, and for causing the actuation portion to manipulate the flow control portion in a manner resulting in the flow control portion affecting flow through the passage. Causing the actuation portion to manipulate the flow control portion is performed dependent upon the engine oil pressure indicating signal and a MELOP threshold computed using said MELOP threshold computing information.
