A portable fuel analyzer includes a sensor, a processor and a display. The portable analyzer receives a fuel sample and the display identifies whether the vehicle fuel is tainted. The portable fuel analyzer is linked to an evaluation unit to determine a frequency measurement based upon signals from the sensor in the portable fuel analyzer. The evaluation unit provides a method of comparing the frequency from the vehicle fuel sensor with the frequency from the portable fuel analyzer. If the green LED is illuminated and the portable fuel analyzer indicates a different frequency than the vehicle fuel sensor, the vehicle fuel sensor is defective and should be replaced; If the green LED is illuminated and the portable fuel analyzer indicates the same frequency as the vehicle fuel sensor, a vehicle component other than the vehicle sensor is faulty; and, if the red LED is illuminated, the mixed fuel sample is tainted and a determination about the vehicle fuel sensor cannot be determined.
