A method and a system for sensing engine oil deterioration are disclosed. The method includes measuring an engine RPM, load (Load), and an engine temperature (Temp), calculating the amount of change in a deterioration factor (f (RPM, Load, Temp) of engine oil per revolution of an engine using the measured engine RPM, load, and the engine oil temperature, and then calculating the engine oil deterioration degree at a current time point by accumulating a value obtained by multiplying the calculated amount in change of the deterioration factor (f (RPM, Load, Temp) by an engine revolutions during a predetermined sampling cycle (Δr) to a previous engine oil deterioration degree.

A computer implemented method system and apparatus for determining remaining life of engine oil in an engine includes generating reference engine profile data by determining reference engine parameters of a reference engine; determining reference engine oil lubrication data based on mechanical testing of an oil sample from the reference engine; generating a reference model by associating the reference engine profile data with the reference engine oil lubrication data; receiving the reference model at an engine apparatus; measuring engine parameters relating to operation conditions of an engine of the engine apparatus; and determining remaining life of engine oil in the engine of the engine apparatus using the reference model and the engine parameters.
