Biodiesel General recommendations and guidelines

Detroit ^® supports biodiesel as a renewable fuel. Biodiesel fuels are mono alkali esters of long chain fatty acids commonly referred to as Fatty Acid Methyl Esters (FAME) and are derived from renewable resources through a chemical process called transesterification.

Detroit ^® approves the use of biodiesel fuel blends as follows:

• DD Family of Engines - Biodiesel blends up to 5% are allowed
• MBE900/4000 Engines - Biodiesel blends up to 5% are allowed
• S60 Engines - Biodiesel blends up to 20% are allowed*

*Engines built prior to MY 2004 may contain materials that are not compatible with biodiesel blends. Biodiesel blends above 5% are not recommended.
