Want to use biodiesel, but have trouble finding local stations? This app's for you. It uses iPhone's location (or a ZIP code) to find nearby biodiesel retailers, telling you which blends are available. It even lets you call the stations directly. How often have you gone to a new station, only to find out they're not open late?Also, check out our paid version, which includes more features for biodiesel users.Made in the USA by a TDI-driving tree-hugger in Seattle, WA. Granola power! What's new Added the ability to search by city. Simply enter in either a five digit zip code, OR a city and state. For example, Cupertino, CA . Whether using city or zip, the app will search for stations near that location. Stations do not have to be exactly in the city, or ZIP, to be found. The size of the search radius is configurable on the Settings screen, as always.
