Further information about country-spe-

Flow improver
Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided. Follow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre.
