quote:"Thank you for visiting the Volkswagen Web site. We appreciate your inquiry on Volkswagen's position on using biodiesel fuel.
B100 stands for 100% biodiesel. It is a diesel fuel derived from biomass feedstock such as soybeans. It can be blended with regular diesel fuel (B20 = 20% biodiesel/80% regular diesel, for example). In Europe our diesel engines are certified to operate any blend of the biodiesel that is available in Europe. European biodiesel is different than biodiesel in the U.S. since it is produced from different feedstock (the rapeseed plant versus the soy plant).
Our parent company does not agree with the specifications for biodiesel in the U.S. and does not recommend its use in any percentage. Using biodiesel will invalidate our warranty.”

There is no difference in the European standard vs. the American standard that would affect performance, nor is there a relevant difference between rapeseed and soy. The reason VWoA is spreading this lie (it's illegal for them to blanket deny a warranty for biodiesel usage, see http://www.ravelco.net/magnusonmossact.htm) is because they are afraid of American biodiesel for one reason only, as far as I can tell, and it's a good one: here in America, the standard (ASTM D 6751, a good standard) is not government-enforced. So, do what you want, but make sure you trust your supplier of biodiesel to sell you only ASTM fuel. As a supplier in Northern California, we often have our fuel tested by laboratories to make sure. Since that's expensive, we are putting together our own in-house lab. As a final comment for you, I'd like to let you know that I happily drive a 2003 VW jetta tdi (on B100 since it was born 16000 miles ago) and it is under the extended warranty. If they ever want to deny it to me, I'll take them to court.
