Case Approves B20 Biodiesel Blends

September 28, 2010

Joe Montesano of Greeneck Earth Works in Tetonia, Idaho, fuels his Case excavator with biodiesel.

Case Construction Equipment approved the use of B20 blends (20 percent biodiesel and 80 percent petroleum diesel) for more than 85 percent of its construction-equipment models.

Biodiesel, which is produced from vegetable oils or animal fat derived from renewable resources, is used in various processed mixes with standard petroleum diesel. This alternative fuel is credited with having the ability to lower exhaust emissions and help reduce dependence on imported oil.

“Biodiesel adds lubricity to the fuel, which is beneficial in many circumstances, particularly as sulfur and aromatics are removed from the fuel,” says Ray Good, engine application manager, Case Construction Equipment. “Biodiesel has a higher Cetane number and burns cleaner with less particulates and smoke emissions.”

Biodiesel fuels must comply with the North American Standard ASTM D6751. “Biodiesel should be purchased from a trusted supplier who understands the product and maintains good product quality,” Good says. “Case recommends that you only use biodiesel from BQ 9000 accredited suppliers to maintain the quality and the consistency of the fuel.”
