Here's a good one for you Tad: Get a diesel vehicle, and for $800.00 you can get a bolt on kit to run it on vegetable oil from restaurants! I have a friend that has a diner near me, and he has a customer with a diesel Golf. The guy stops by periodically and fills up on used peanut oil from the friolator! The car still has it's original diesel tank seperate from a new one for the friolator oil, and uses both. I don't know what the figures for milage are but I bet it's the cheapest vehicle going! The other thing I wonder about is winter performance as my old diesel Rabbit had a lot of trouble with the New England winters. Did a fine job pulling my cats in Summer though! Brian
