GM Supports B20

GM Supports B20

Next year's heavy-duty diesel vehicles will be compatible with 20% biodiesel.

General Motors told biodiesel supporters at the National Biodiesel Conference in Grapevine, Texas that the company's 2011 model year Duramax 6.6L turbo diesel engines will be fully compatible with a 20% blend of biodiesel. The announcement covers all 2011 GM heavy-duty products including Chevrolet Silverado, GMC Sierra, Chevrolet Express, and GMC Savana. GM joins Ford and Chrysler in formalizing its support for B20.


Mike Robinson, vice president, Environment, Energy and Safety Policy for GM, says they are seeking different paths to fuel solutions in order to maximize efficiency, reduce emissions and minimize the dependence on petroleum. Steve Howell, technical director for the National Biodiesel Board called GM's support for B20 a huge win for the biodiesel industry.


According to the National Biodiesel Board, over the past seven years, a tremendous amount of cooperative effort has taken place between the biodiesel industry and the auto and equipment manufacturers to secure broader support for B20 blends in their vehicles. From the development of stringent new ASTM specifications for blends up to B20, to intensified fuel quality enforcement efforts and emphasis on the BQ-9000 program.
