E-free attempts to locate at least 5 stations, that sell ethanol-free (E0) gasoline.

These stations, will be the ones closest to the center of the map, and within a 100 mile radius.

If the GPS service on your device is turned on, the E-Free can track your current location, keeping it centered in the map. As long as your GPS service is running, this tracking and centering feature can be turned on or off within E-Free as needed.

If tracking is turned off, or your GPS service is not running, you can scroll the map to other locations, and E-free will search for stations based on the new map center.

The location of a station listed as selling ethanol-free gas can be passed to your phone navigation software, such as Google Maps Navigation, for turn-by-turn directions.

Users may request adding and removing stations from within the application.

Requires that your Android device has an SD card installed, and mounted.
