A method to obtain average revolutions per independent unit includes a total number of engine revolutions with the engine control unit (ECU) (4) and a current odometer value with the ECU (5) so that a final value can be calculated by dividing the total number of engine revolutions with the current odometer value for a designated time period (6). The current odometer value can be a distance unit (13) or time unit (14) as the final value, which is the average revolutions per independent unit, is displayed with a control panel of a vehicle (7). The final value provides an accurate conclusion regarding the current condition of an engine in addition to the mileage of the engine or the engine hours.
