2011 Ford Super Duty Offers Additional Fueling Option

Praised by the manufacturer as delivering best-in-class diesel, the 2011 F-Series Super Duty is now getting all the attention again, as Ford announced that its 6.7-liter Power Stroke V-8 turbocharged diesel engine is B20 biodiesel compatible.

According to Ford, this means that customers get an additional fueling option that uses blends of up to 20 percent biodiesel and 80 percent petroleum diesel.

During the Super Duty's development, engineers put more than 10.3 million equivalent test miles on the new diesel engine, including extreme road and weather conditions. The engineers also used customer data such as driving styles, road types and vehicle usage (towing and payload) in the testing program.

Because biodiesel fuel varies in quality in the U.S. and Canada, durability testing cycles were run on multiple blends of the fuel, Ford says.

"The entire vehicle was extensively tested on B20 to ensure compatibility of the vehicle fuel system components, including fuel filters, lines and connections," said Ed Waszczenko, lead diesel engine durability engineer. "Each component that is exposed to the fuel was tested in a 'worst case' proprietary fuel mixture to prove compatibility and durability."

Ford, however, assures its customers they will still benefit of top performance even if going for a more environmentally friendly fuel. The new 6.7-liter Power Stroke V-8 turbocharged diesel engine is rated at 735 ft.-lb. of torque at 1,600 rpm and 390 horsepower at 2,800 rpm.

"The customer will not see any degradation in performance with biofuels up to B20," Waszczenko said. "Also, testing was conducted to simulate how some customers will use biofuels. This included switching from normal diesel fuel to B20 fuel, just like a customer might do."
