I actually saw a guy doing this 2 weeks ago. He goes around to all local restaurants who normally pay to get rid of the stuff and takes it off their hands for nothing. He puts it in barrels and told me that he uses it in his truck. He said he had to have conventional diesel to start the truck, and after it was started he could switch over to the home made fuel for driving it. Seems like a clever idea. It isn't a solution though because if everyone did that there wouldn't be enough of a supply of such oil because everyone and their brother would be looking for it.

True enough. Supply and demand.
