Thats about $600 that Ive saved in fuel in just a few months,
I have to admit it feels kind of good, ... I'm still running on my first tank of diesel fuel and I've put over 7,000 miles on the car.
I wasn't really looking at it solely to save fuel costs, but the renderer who was picking up our dirty vegetable oil at the store told us he was going to start charging, so I decided to look into the car as a way to use our used cooking oil,
Its pretty difficult to spend 40 or 50 bucks on a tank of fuel when I can get it for free,
