Say diesel cost $1.70 per gallon. You can make biodiesel for about $ 0.70/gallon
If you factor the cost to produce it into your cost per mile, it is like getting 2.33 times the mpg.
So if you are getting 15 mpg with diesel, the lower cost of biodiesel, for the same expense is like getting 35 mpg.
Plus, if you don't mind making biodiesel, you money stays in the USA.
