The boat I was in when I was only driving the Benz was this:
When I first converted the Benz to WVO 3 years ago veggie oil was everywhere and I had no problem working out a deal with restaurants to pick it up. Diesel was at around $2.25 around then and I had this great feeling of energy independence...Then all of a sudden when diesel shot up to $4 or $5 bucks a gallon there is this big "green" movement where everybody wants to use alternative fuels, most namely SVO because it was "free." Well, if you are stealing it from a restaurant that has worked out an agreement to give it to someone else, yeah, I guess it was free for a lot of people. Anyway, WVO is limited to a niche market and is not the answer to energy independence. That being said, I'm still toying with the idea of converting the SMB to veggie...
