Cummins has approved biodiesel B20 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 upgraded its previous position on the use of biodiesel fuel, which had limited the use to B5 blends only, up to B20 for three 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 with confidence using B20 fuel.

“We have completed exhaustive analysis and test evaluations which enable Cummins to provide the necessary guidance and information to our customers for the proper and successful use of this fuel in our engine,” said Edward Lyford-Pike, Chief Engineer, Advanced Alternative Fuel Programs. “This will enable our customers to have a choice that includes renewable fuel.”
