Well, most what is sold as vegetable oil is a mixture of oils anyway - it can have anything from palm to cottonseed to canola to soy oil, so no, it really doesn't matter. Chemically, vegetable oil is an ester of glycerol with three fatty acids, and the length and saturation of the fatty acids are what gives the oil its characteristics. However, they're much more similar than they are different, and biodiesel can be made from any of them. DK
