B20 Approval For Volvo EPA 07 Certified Products
Volvo engines are certified to comply with U.S. EPA and California emissions standards
based upon the use of test fuels with specifications established by these regulatory agencies.
Alternative fuels, including biodiesel, that are not substantially similar to the required test
fuels may adversely affect engine emissions compliance. As a result, Volvo does not warrant
the engine will conform to applicable Federal or California emissions limits when operated
on biodiesel or other alternative fuels that are not substantially similar to specified test
fuels used for certification.
However, the use of biodiesel up to a maximum of 20% (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.
