From MB operators manual:
Additives for approved service products are
neither required nor permitted. Approved fuel
additives are the exception. Additives can
cause engine damage and must therefore not
be added to the service products.
The use of additives is always the
responsibility of the vehicle operator. The use
of additives may result in the restriction or
loss of your Limited Warranty entitlements.
Do not mix such fuels with diesel fuel and
do not use any special additives. This can
otherwise lead to engine damage. This
does not include flow improver additives.
For further information, see "Flow
Flow improvers are fuel additives used to
improve the flow characteristics of diesel
The effectiveness of flow improvers cannot be
guaranteed with all fuels. Observe the
Information about approved flow improvers is
available from any authorized Sprinter Dealer.
At outside temperatures below 14 ‡ (Ò10 †),
and if using diesel with less resistance to low
temperatures, add flow improver, basing the
mixing ratio on the outside temperature.
Mix this fuel additive with the diesel in good
time before the flow properties of the diesel
are affected by paraffin separation.
Malfunctions resulting from paraffin
separation can only be rectified by heating
the entire fuel system. Park the vehicle in a
heated garage, for example.
