Biodiesel leaves higher levels of ash in diesel particulate filters
and may require more frequent diesel particulate filter (DPF)
regeneration and cleaning. Biodiesel can cause deviations in
temperatures and functionality of the DPF burner and may cause
fault codes or errors.
Biodiesel exhaust gas is aggressive to some materials used in
selective catalytic reduction systems (SCR) and may require
more frequent cleaning, repairing or replacing of SCR parts.

Biodiesel has a high viscosity at temperatures below 0 ˚C (32 ˚F)
and may cause problems starting the engine. Use a fuel heater
or park machines in a heated building if possible.

Biodiesel B100 has about 8% lower energy density compared to
regular diesel fuel. Blends equal or lower than B20 have a small
impact on engine performance.

Engines are certified to comply with U.S. EPA, California and EU
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 that
the engine will conform to applicable Federal or California and EU
emissions limits when operated on, or having previously being
operated on, biodiesel or other alternative fuels that are not
substantially similar to specified test fuels used for certification,
nor if biodiesel / regular diesel is used in blends that exceed the
recommendations.
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 or emissions system, provided the bio fuel
used in the blend conforms to the applicable standards and the
additional steps outlined herein are followed.
