The VMO is advantageously arranged to receive the signals from the on-board diagnostics (OBO or OBO-II or equivalent) port. The VMO is preferably programmed so that the performance coefficient is used to calculate the instantaneous and/or cumulative quantity or percentage of fuel wasted as a result of non-optimum operation of the vehicle.
