4.2 Fuel Operating Media
4.2.1 Quality
Use commercially available diesel fuel with less
than 0.5% sulphur content. If the sulphur content is
higher, oil change intervals should be reduced (see
6.1.1).
The following fuel specifications / standards are
approved:
● DIN EN 590
● BS 2869
● ASTM D 975-96; 1-D and 2-D
● NATO Code F-54 / F-34 / F-44 and XF 63
Exhaust emission values which may be determined
in the case of type approval tests always refer to the
reference fuel prescribed by the authorities for the
type approval test.
4.2.2 Winter-Grade Fuel
Waxing may occur at low temperatures, clogging
the fuel system and reducing engine efficiency. If
the ambient temperature is less than 0°C, winter-
grade fuel (suitable down to -15°C) should be used.
(This fuel is usually available from filling stations
well in advance of the cold months). Diesel fuel
containing additives (Super diesel) is often on sale
as well, for use down to -20°C.
● At temperatures below -15°C to -20°C, kerosene
should be added to the diesel fuel. The relevant
percentages are given in the adjacent diagram.
If summer-grade diesel fuel must be used at tem-
peratures below 0°C, up to 60% kerosene can be
added (see diagram).
In most cases, adequate resistance to cold can also
be obtained by adding a flow improver (additive).
Please inquire at DEUTZ SERVICE.
Diesel fuels must never be mixed
with petrol (Normal and Super
grades)!

Mix in tank only! Fill with the ap-

then add the diesel fuel.
