- Always follow the manufacturer’s storage
recommendations and “best-before” dates for
each delivery of biodiesel.
Effects of biodiesel on exhaust after-treatment
systems
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.
Effects of biodiesel on cold weather operation
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.
Effects of biodiesel on emissions compliance
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.
