ABSTRACT:
A method for dispensing fuel has features to prevent theft of fuel and also control maintenance of authorized vehicles. The system includes a portable memory unit which remains with each vehicle. The portable memory unit is removably connected to an on-board computer on the vehicle. The on-board computer senses certain vehicle conditions and changes through transducers carburetor settings. The on-board computer also writes into the portable memory unit a warning if any of the vehicle conditions exceed limits. At the fuel dispensing site, a data processing unit receives the portable memory unit to read from it coded information. A central processing unit is located at a central records site and connected to the remote processing unit for record storage. The remote processing unit reads from the portable memory unit a last mileage at which fuel was dispensed, and compares it to a current mileage entered by the operator into the remote processing unit. A next service mileage is also read by the remote processing unit and compared to the current mileage. If the current mileage exceeds a next service mileage or if warnings are read by the remote processing unit, the operator is notified to immediately take the vehicle to a maintenance facility for maintenance.
