2011 Duramax to Run on B20 Biodiesel Fuel
GM, Ford and Dodge diesel trucks feature biodiesel compatibility.

February 8, 2010

General Motors announced today at the National Biodiesel Conference that all 2011 Duramax-powered diesel trucks will be compatible with B20 biodiesel fuel.

The National Biodiesel Board developed B20 and tested it over the past five years in fleet applications. B20 is a mixture of 20 percent biodiesel and 80 percent regular diesel. Biodiesel is produced from fats and oils that are byproducts of agricultural and livestock production. Using biodiesel reduces carbon dioxide emissions compared with petroleum diesel..

Chrysler has produced fleet trucks since 2007 compatible with B20. And last fall Ford announced that their 2011 Ford F-series Super Duty diesel pickups are approved for B20 fuel. These domestic manufacturers produce more than 80 percent of diesel light vehicles sold in North America..

To make the Duramax engine compatible with B20 required several upgrades, including changes to seal and gasket materials, a new fuel filter design as well as additional heating for the fuel system..

The new Duramax engine will be available in heavy-duty versions of the Chevy Silverado and GMC Sierra pickup, in addition to the Chevrolet Express and GMC Savana full-size vans.
