B5 Approval For Mack US10 Certified Products

Mack 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
and may impact the performance of certain emissions aftertreatment components. As
a result, Mack does not warrant the engine will conform to applicable Federal or
California emissions limits when operated on, or having operated on, biodiesel or
other alternative fuels that are not substantially similar to specified test fuels used for
certification.
The use of biodiesel up to a maximum of 20% (B20) in and of itself, will not affect
the manufacturers mechanical warranty as to engine and emissions system related
components except as limited below with respect to aftertreatment components,
provided the bio fuel used in the blend conforms to ASTM D6751 and B1 to B5
blends conform to ASTM D975, and B6 to B20 blends conform to ASTM D7467.
Failure of certain emissions aftertreatment components, specifically SCR, DPF and
NOx sensors will not be warranted if the failure can be attributed to operation on
biodiesel blends from 6 to 20% (B6 to B20) even if the biodiesel used in the blend B6
to B20 conforms to ASTM D7467 or any related standard.
