Abstract: To be used with an internal combustion engine having an oil reserve wherein engine oil is contained, and an engine internal oil pressure system structured to distribute lubricating oil to the wearing parts of the engine from the oil reserve of the engine, a pre-starting lubrication system which includes an oil reservoir to contain a quantity of engine oil to be supplied through an oil flow corridor of the reservoir to the engine internal oil pressure system for pre-starting lubrication of the wearing parts of the engine. The pre-starting lubrication system is structured to constantly maintain an acceptable supply of oil within the reservoir and will supply pre-starting lubricating oil upon a flow of pressurized air being directed into the oil reservoir, through an air flow corridor, so as to displace oil contained in the reservoir out through the oil flow corridor for pre-starting lubrication of the engine.
