I was telling a friend of mine about this guy on the show "Dirty Job" making his own bio diesel. So he checked it out and is making bio diesel at home for his dump trucks and has cut his fuel cost to .60 a gallon. He did tell me that if you pull up behind him in a car you smell french fries. He go's around to about 10 different place's to get their used veggy oil for free, and then makes it up for his 2 dump trucks. That would be nice if we could do that on the road lol. Go into Mc Donalds and say I will take a small coke and all your used veggy Oil togo. lol
