Indication of possible vehicle running distance with remnant fuel is accomplished by measuring the fuel amount, the fuel consumption and the running distance and calculating the possible remaining running distance with remnant fuel. The indication is directly based on the current driving condition so that the driver can know the possible running distance with remnant fuel in continued driving under similar conditions. The indication can prevent fuel shortage and also teach a driver economic driving.

A method of indicating a remaining possible vehicle running distance available on the remnant fuel of a vehicle comprising the steps of: measuring the amount of fuel consumed; measuring the remnant fuel amount in a fuel tank; measuring the running distance the vehicle has run; storing the measured remnant fuel amount when either one of the measured consumed fuel amount and the measured running distance has reached a predetermined value; generating a train of pulses after said storing step, one cycle period of the train of pulses being determined by the other one of the measured consumed fuel amount and the measured running distance; calculating a time interval in which the number of pulses in the train of pulses reaches the stored remnant fuel amount, said time interval being proportional to a remaining possible running distance available on the stored remnant fuel amount; and indicating the calculated remaining possible running distance by an indicator.
