Abstract

In an engine oil level adjusting apparatus including an oil pan (3) provided to a lower portion of an engine main body (1), a sub tank (5) communicating with the oil pan, and oil feeding means (6) for selectively feeding engine oil between the oil pan and the sub tank in both ways, there are provided viscosity measuring means (7) for measuring a viscosity of the engine oil in the oil pan, amount-of-remaining oil detecting means (8) for measuring the amount of engine oil in the oil pan, and control means (9) for determining an appropriate oil level in the oil pan on the basis of the viscosity of engine oil obtained by the viscosity measuring means and for driving the oil feeding means so as to obtain the appropriate oil level.
