Herein disclosed in an oil degradation warning system which comprises several sensors for sensing parameters which are closely related to degradation factors of the engine oil, a microcomputer which processes the detected parameters to compute oil degradation coefficients of them in each factor, integrates the oil degradation coefficients in each factor with passage of time, and issues an instruction signal when at least of the integrated values of the oil degradation coefficients exceeds a corresponding reference value, and a warning device which gives a warning when the instruction signal is applied thereto.
