Cummins approved biodiesel B20 blends for use in its 2002 and later emissions-compliant ISX, ISM, ISL, ISC and ISB engines. This includes recently released 2007 products. Cummins says it is able to upgrade its previous position, which limited use to B5 blends, to B20 for three key reasons. First, the American Society of Testing Materials specification ASTM D6751 now includes an important stability specification for B100 biodiesel. Second, the availability of quality fuels from BQ-9000 Certified Marketers and Accredited Producers is growing rapidly; and third, Cummins has completed the necessary testing and evaluations to ensure that customers can reliably operate their equipment using B20 fuel.
The popularity and use of biodiesel fuel continues to climb. Recent studies predict that by 2008, 1.2 billion gallons of B100 biodiesel will be produced in the United States. Find out more about Cummins at www.everytime.cummins.com.
