WASHINGTON -- Volkswagen AG says diesel fuel containing 5 percent soybean oil or other natural farm products is suitable for all of its diesel engines in the United States.
Consequently, the company is affirming that its warranties apply to engines that use the fuel, known as B5 biodiesel.
In addition, Volkswagen and agricultural products firm Archer Daniels Midland Co. are agreeing to research the suitability of biodiesel containing as much as 20 percent farm products, called B20.
The announcements were made today in Washington by Frank Witter, CEO of Volkswagen of America Inc., and Allen Andreas, CEO of ADM.
The two companies began a joint research program in early 2004.
Results of the research, and commitments by the biodiesel industry to meet technical specifications, enabled Volkswagen to assure owners that warranties will cover engines run on B5 biodiesel, company officials said.
Biodiesel burns cleaner than fuel made entirely from petroleum, but VW still has work to do on diesel pollution controls to meet tougher U.S. emissions standards being phased in by 2009, a company spokeswoman acknowledged.
