When changing to a higher alloyed oil quality after a
longer period of operation, it is recommended to per-
form the first oil change of the higher quality oil already
after 25 operating hours.
6.2.2 Fuel
6.2.2.1
Fuel quality
The following fuel specifications are permitted:
n
EN 590
n
ASTM D 975 Grade 1-D/2-D
n
BS 2869 A1/A2
With respect to the percentage (ppm) of sulphur the fuel used in
the engine must comply with all relevant exhaust emission regula-
tions in the are of use of the engine.
6.2.2.2
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.
6.2.2.3
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.
