Use of biodiesel in John Deere engines explained

John Deere Power Systems is officially clarifying its position on the use of biodiesel in its diesel engines.

Biodiesel is a renewable, oxygenated fuel made from agricultural resources such as soybeans or rapeseeds. It is biodegradable and free of sulfur.

“Using biodiesel fuel reduces particulate emissions and decreases dependence on crude oil,”
said Brian Brown, manager of worldwide marketing support at John Deere Power Systems.

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. This includes all non-emissions-certified engines. Biodiesel blends up to B20 can be used only if the biodiesel meets ASTM D6751 (U.S.), EN 14214 (EU) or equivalent specification.

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.
