Fuel prices not bothering me much at all. My biodiesel cost me right at $1.00 per gallon to make. My wife drives the Excursion 7.3l, 44 gallon tank which averages about 14 MPG in town and 16-18 on HWY. So anywhere from 600-750 miles per tank. Only cost $44 per fillup plus about 2 hours a week to make the biodiesel. NOT BAD! I drive a 96 Ford Explorer. Just turned 257,000 miles, I have put all but the first 32,000 on the car. Not bad either! Gets around 17 per gallon. This car is on it's last leg! As soon as it dies(which sometimes I think it never will) I will be replacing it with a diesel mercedes probably? Then I will be totally non relient on any for of foreign oil. I will then be saving enough money each month to make most peoples head spin!
