Can any vehicle be modified to run on VO?
Gasoline engines cannot be modified to run on VO. Any diesel engine is a candidate for VO modification. • Cant I just put VO in my factory diesel tank? We dont recommend it. Why not? For one, theres no heat in your diesel tank. Secondly, VO and diesel do not mix well. And thirdly ummm, theres no heat in your diesel tank! The whole idea of the two-tank system is to get your VO up to the proper temperature for combustion. • What if I want to modify my factory tank instead of adding a second tank for VO? Weve seen this done successfully, but the legality of modifying a stock fuel tank is questionable. • What kind of mileage/horsepower/torque will I get with a modified vehicle? It should not differ significantly from that of an unmodified vehicle. • Why do some VO systems have a backflush feature? This has to do with the properties of vegetable oil. When hot, its a great lubricant for moving engine parts, and it burns beautifully. But when cooling, VO can leave a nasty residue in fuel line
