Mack and Volvo Trucks join growing list of B20 supporters

By NBB | May 01, 2012

The B20 domino effect continues! Two more original equipment manufacturers (OEMs) have formally expressed approval for B20. Heavy-duty truck makers Volvo Trucks North America and Mack Trucks Inc. have confirmed their B20 approval and made their updated warranty statements available to the National Biodiesel Board, as well as to Volvo and Mack dealers and customers. With the addition of these two OEMs, now more than 65 percent of diesel vehicle manufacturers in the U.S. market support B20 or higher biodiesel blends.

Volvo and Mack are among the first OEMs to extend B20 approval both to their new 2010 EPA emissions certified engines featuring selective catalytic reduction technology, as well as to their older legacy models. The following warranty statement applies to Volvo Trucks’ D11, D13, and D16 engines, as well as to Mack’s MP7, MP8, and MP10 engines: “The use of biodiesel up to a maximum of 20 percent (B20) in and of itself, will not affect the manufacturer's mechanical warranty as to engine and emissions system related components, provided the bio fuel used in the blend conforms to ASTM D6751, B1 to B5 blends conform to ASTM D975, and B6 to B20 blends conform to ASTM D7467. Please note that engine and aftertreatment emissions system component warranties are valid providing the B20 blend meets the respective ASTM standard. Customers will need to utilize oil sampling to establish appropriate drain interval(s) for their specific application(s).”

Volvo Trucks North America and Mack Trucks Inc. are part of the Volvo Group, one of the world's leading manufacturers of trucks, buses and construction equipment, drive systems for marine and industrial applications, aerospace components and services, and one of the world's leading producers of heavy-diesel engines (9-16 liter). The Volvo Group’s operations and products are guided by the company’s three core values: quality, safety and environmental care.
