Deere Power Systems & Biodiesel

Posted on November 15, 2007

Due to the variety of standards that exist in the diesel engine industry and in response to questions from various markets, John Deere Power Systems (JDPS) is officially clarifying its position on the use of biodiesel in its diesel engines.

While 5 percent blends (B5) are preferred, biodiesel concentrations up to a 20 percent blend (B20) in petroleum diesel fuel can be used in John Deere engines through Tier 3/Stage III A models, including all non-emissions-certified engines, the company said.

Biodiesel blends up to B20 can be used only if the biodiesel (100 percent biodiesel or B100) meets ASTM D6751 (U.S.), EN 14214 (EU) or equivalent specification. Deere added that it recommends that biodiesel users are strongly encouraged to purchase biodiesel blends from a BQ-9000 Certified Marketer and to source from a BQ-9000 Accredited Producer, as certified by the National Biodiesel Board.

John Deere-approved fuel conditioners containing detergent/dispersant additives, such as John Deere Premium Biodiesel Fuel Conditioner, are recommended when using lower biodiesel blends but are required when using B20 blends.

“We still get questions about higher biodiesel blends and warranty, but our position on warranty for customers that use B20 has not changed,” said Grant Suhre, manager of field service for JDPS. “While we prefer the use of B5 biodiesel blends, we also know that when high quality B20 blends are available, they work well in John Deere engines. If customers make sure the biodiesel meets the ASTM D6751 standard, is stored and mixed properly, and is used shortly after manufacture, they can continue to rely on John Deere engines while using B20.”
