I think any variation of diesel fuel, is still diesel fuel. By people posting bio-diesel topics here, it would give people some possibly good ideas. I am not a "tree hugger" per say, but I do like the idea that our cars would run on a plant product that we can grow over and over again. Someone posted about be really low of diesel, stoped at a local convience store, bought 3 bottles of Crisco veg. oil and drove on. Remember, Rudolph Diesel first used peanut oil as the fuel for his new type of engine.
