PURPOSE:To suitably indicate the time of exchanging engine oil by providing a reset switch to reset the integrated value of the coefficient of deterioration of the engine oil into an initial value and an initial value setting means to set the integrated value at a special time as the initial value. CONSTITUTION:A microcomputer 6 inputs a detecting signal from each of sensors 2-4, and finds out each coefficient of deterioration of engine oil to add up it together, and integrates each added up value with passage of time. When the above integrated value exceeds a set standard value, the microcomputer 6 sends out an output signal, an initial value setting means sets a value proportionate to the integrated value just before then as an initial value. An alarm lamp 8 lights up on receiving the output signal from the microcomputer 6 to warn of the time of exchanging the engine oil. |
