I read about this company several years ago, and did some research. At the time, I thought it would be neat to do…now, with the proce of fuel, I wish I would have! Check them out…they offer bolt-on kits to make your diesel engine run on vegetable oil.
Won’t work, you say? Well, do some research. You’ll find out that the diesel engine was originally invented to run on peanut oil. It was only after oil and refining discovered was it converted to run on diesel fuel.
