8.3.2 Fuel
8.3.2.1 Fuel quality
We recommend using a diesel fuel with a sulphur content of less
than 0.1 %.
When using a diesel fuel with a high sulphur content of 0.5 % to
1.0 % the oil change intervals must be halved.
Fuels with a sulphur content of more than 1.0 % are not permitted.
In order to fulfil national emission regulations one must strictly use
the legally required fuels (e.g. sulphur content).
For engines used in EPA areas, the use of diesel fuels with ultra-
low sulphur content is mandatory (ASTM D975 Grade-No. 1-D S15
and 2-D S15).
(EPA: United States Environmental Protection Agency)
The recommended Cetan index number is 45. A Cetan index
number higher than 50 should preferably be used, especially at
ambient temperatures below -20 °C (-4 °F) and when working at
altitudes of more than 1500 m (4921 ft).
The following fuel specifications are recommended:
n EN 590
n ASTM D975 Grade-No. 1-D and 2-D
8.3.2.2 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.
8.3.2.3 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.
