You could always just brew your own, it comes out to about 0.90 USD per gallon if you find the best deals on methanol and Lye. You could also use ethanol to brew it, and that would allow you to save even more, since you can get grain ethanol from most farmers free.

So where's the manufacturing impact if you're using a naturally occuring alkali and alcohol that comes from rotting silage?

Besides, by the time you get done filtering out the WVO, doing everything else that some people like to do with it, and then spending assloads of money on building a fuel system that will accept it, and in some cases, still having problems with it, it's just cheaper, easier, and more friendly to everyone (except some random company that's making a profit from their fuel systems) to make your own BD. Now, if you don't have the means to do it, that's another story, but I will never advocate using WVO/SVO for fuel, and neither does the US EPA. It's not approved, and if you're caught using it, you face penalties, fines, and jail time.
