Cummins approves use of B20 blends

Engine maker Cummins Inc. announced in March the approval of B20 biodiesel blends for use in its 2002 and later emissions-compliant ISX, ISM, ISL, ISC and ISB engines. This includes the recently released 2007 products. Cummins is able to upgrade its previous position on the use of biodiesel fuel, which limited the use to B5 blends only, up to B20 for three key reasons. First, ASTM D6751 specification 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. Third, Cummins has completed the necessary testing and evaluations to ensure that customers can reliably operate their equipment with confidence using B20 fuel. (March 22, 2007)
