try living in new zealand.
we get third hand oil, for roughly 4US dollers per litre.
but on a better note, A guy here has invented a car that runs off vegetable oil. But hopfully he wont be brought out by oil companys like aguy ten years ago that invented a car that runs off water.
Oil companys brought him out, so legally he cant tell people how or what he used to make it work.
Nz'ers are so wise
