The picture is taken just outside of Salt Lake City Utah where i live. The regular offroad is a dollar less than regular diesel like you would expect. The bio off road is nearly 2 dollars more. There are two gas stations within a mile of each other that have pumps like this. Its starting to become more popular here in the summer. In the winter you can forget it.
