1.
How do I know if my car is suitable for biodiesel?
Nearly all diesel cars from VW, Audi, SEAT
and Skoda sold after 1996 and classified in
a lower emission class than EURO 4 (excluding
EURO 4) are suitable for biodiesel. Vehicles
with self-regenerating particulate matter
filter systems (EURO 4) are not approved for
biodiesel. More information about passenger
cars which can be operated with biodiesel
can be downloaded here.
2. Is it allowed to
mix fossil diesel with biodiesel in the tank?
Yes. Both fuels are characterized by similar
structures and therefore mixable in any ratio.
3. Is consumption of
biodiesel higher?
The energy content of biodiesel is slightly
lower than the energy content of fossil diesell.
Thus, biodiesel consumption is increased by
5% at maximum.
4. Does biodiesel harm
my engine?
No. The oxygen content of 11% improves combustion.
This results in lower deposits and soot.
5. Where can I refuel
biodiesel?
In Germany, more than 1.900 gas stations offer
biodiesel. An overview can be found under
www.biodiesel.de.
