摘要： Provided is a method for detecting a condition of engine oil that allows the progress of degradation of engine oil to be more accurately determined without incurring any significant cost. In a method for detecting a state of engine oil by defining a degradation index that changes with a progress in degradation of the engine oil that lubricates an internal combustion engine and determining a progress of the degradation of the engine oil according to the degradation index, a value related to a concentration of blow-by gas that flows into a crankcase of the engine is computed, and the degradation index is computed according to the computed value related to a concentration of blow-by gas that flows into a crankcase of the engine. The degradation index may consist of a total base number of the engine oil, and the concentration of blow-by gas that flows into a crankcase of the engine may consist of a NOx concentration.
