The system includes a device connected to a vehicle which includes a mileage tracking component connected to a central processor having suitable memory associated therewith for receiving and storing an input from the mileage tracking component as input data corresponding to mileage traveled on the vehicle. The device further includes operating software thereon and low power use detector operably connected to a battery on a vehicle for supplying power to said system in one of a normal power use mode and a low power use mode. Also, operably connected to the power supply and the mileage signal generating device is a detector which indicates when the vehicle is in a generally non-mobile state and causing the system to enter into said low power use mode.
