An electronic device for recording the fuel usage of a vehicle capable of operating on multiple fuel types. The invention tracks time, distance, and fuel mixture information in association with the type of fuel used by a multi-fuel vehicle. The device generally consists of a power supply; an electronic system clock; a data storage component; one or more connections to the vehicle which determine when the motor is running, which fuel type has been selected, which fuel type is being burned, the relative fuel content, and fuel performance information; a signal interface for converting analog vehicle signals to digital signals; an analog-to-digital convertor; a microcomputer to interpret the digital signals; a system logic control circuit for coordinating the writing of information to the data storage component; an external data interface for direct or indirect access to the contents of the data stored in memory; and a visual display.
