8.2.2.2 Winter fuel
For winter operation use only winter diesel fuel, to avoid clogging
because of paraffin separation.
At very low temperatures disturbing paraffin separation can also be
expected when using winter diesel fuel.
Diesel fuels suitable for temperatures down to -44 °C (-47 °F) are
available for Arctic climates.
NOTICE!
Danger of engine damage!
– The admixture of petroleum and the addition of
“flow enhancing additives” (fuel additives) is
not permitted.
8.2.2.3 Storage
Even traces of zinc, lead and copper can cause deposits in the
injection nozzles, especially in modern Common-Rail injection sys-
tems.
Zinc and lead coatings in refuelling systems and fuel lines are not
permitted.
Copper containing materials (copper lines, brass items) should be
avoided, because they can cause catalytic reactions in the fuel with
subsequent depositing in the injection system.
8.2.3 Oil for exciter shaft housing
Use only engine oils according to the following specifications:
n API CI-4 or higher quality
Avoid mixing engine oils.
NOTICE!
Components may get damaged!
– Do not use low-ash engine oils for the exciter
shaft housing.
Maintenance – Fuels and lubricants
