In general, the EPA testing of the Gastell Device did not show a positive benefit from its use. None of the Phase I chassis Dynamometer tests with the device installed showed a positive fuel economy effect. Four vehicles of varying size and power-to-weight ratio were road tested in San Antonio (with from one to two drivers each) and only one vehicle/driver combination showed a fuel economy improvement (5%). It is concluded from the test data available that only drivers with aggressive driving behavior (or other driving habits that involve excessive throttle manipulation) could benefit from use of this device and then only if: (1) their vehicle happened to have the fuel economy response characteristics that favorably matched the activation setting of the device, and (2) the driver consistently responded to the device signal and refrained from such aggressive driving.
