I believe I have found an alternative to the high prices we pay at the pump. As I drive a truck with a diesel engine, I have been waiting since winter ended for the price of diesel to come down as it tends to compete with home heating oil in the winter. This year it never came down...and runs about $4.59 a gallon. I finally made a move when it took $100 to fill my tank: http://www.greasecar.com SVO (Straight Vegetable Oil) is a renewable fuel source and you can, with a little work, get it for free. Check it out...and let's put the oil companies out of business!
