Ed Waszczenko, Ford lead engine durability engineer, noted that B20 biodiesel compatibility is being added for the 2011 model year. That means the new 6.7-liter Power Stroke can be operated on a biodiesel blend of 20% biodiesel and 80% regular petroleum diesel.

According to Waszczenko, the new turbodiesel boasts an average 18% improvement in fuel economy for pickup models and an up to 25% improvement for chassis cabs vs. 2010 Super-duty models, In addition, he said trucks equipped with Ford’s new 6.2-liter V-8 gasoline engines will deliver an average 15% fuel economy improvement over the OEM’s comparable 2010 models.
