Bethesda, Maryland -- Diesel fuel additives that are not clearly labeled as approved for use in model year 2007, or newer engines, should not be used in new diesel motor vehicles according to the Automotive Specialty Products Alliance (ASPA).

ASPA made the announcement to coincide with the implementation of new ultra low sulfur diesel fuel requirements that went into effect June 1, 2006 that will enable 2007 model year, or newer, diesel (on-road) engines to reduce emissions by more than 90 percent.

Under the Environmental Protection Agency (EPA) regulations after June 1, 2006, diesel fuel additives are required to include label information related to acceptability of use in 2007 model-year diesel engines. ASPA members are working with their point-of-sales partners and others to alert diesel equipment operators and others as to the proper use of additives in model-year 2007 diesel engines.
