I have an F250 Powerstroke 7.3L diesel that I have modified to run on waste vegetable oil (WVO) from restaurant fryers. I have 135,000 miles on veggie oil. Total miles : 335,000. Original injectors, original transmission. In the 10 years that I have run on free fuel, I saved over $25,000 in fuel costs. Which paid for my 1LT RS.
Essentially, I have a 2nd fuel system installed. Veggie tank, veggie fuel pump, veggie fuel filter and a switching valve to switch between diesel and vegetable oil.
Switches in the cab allow me to change fuels on the fly.
Also have water injection installed.
