First of all E-85 is not biodiesel, it's a mixture of gasoline and ethanol. Ethanol is corn alcohol, and since years back the US government subsidized corn farming, people were figuring out shit they can make out of it since the US can produce so much of it.
And you can't put diesel in a gas car just like you can't put gas in a diesel car. Do you guys have even a remote clue on how an internal combustion engine works and the difference between a gas and a diesel engine? You have any clue the diffrence between diesel and gasoline? Any of you ever seen and touch diesel fuel?
Now if you had a shot at refining your own crude oil, you would be more likely to do it with diesel . Gasoline requires a much greater refining process than diesel fuel.
