Do diesel fuel additives have to be ULSD compliant?
Yes. The EPA mandates that all diesel fuel additives contain one of two statements depending on ULSD compliance. Compliant is defined as the additives itself being less than 15 ppm in sulfur content. Those diesel fuel additives that are compliant have this statement: This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines. Those additives that are greater than 15 ppm in sulfur content are deemed non-compliant and must have this statement: This diesel fuel additive does not comply with federal ultra-low sulfur content requirements for use in model year 2007 and newer diesel motor vehicles or model year 2011 and newer diesel nonroad equipment engines. All Power Service diesel additives are ULSD compliant. Information provided by: Power Service Products, Inc.
