Fuel - Case WX145 Operator's Manual

SECTION 4

FUEL

Use commercially available diesel fuel with less than
0.5% sulphur content. If the sulphur content is
higher, oil change intervals should be reduced. The
following fuel specifications
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
fuels prescribed by the authorities for the type
approval test.
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 (32 °F), win-
ter-grade fuel, suitable down to -15 °C (5 °F), should
be used; this fuel is usually available from filling sta-
tions 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 (-4 °F).
- At temperatures below -15 °C to -20 °C (5 °F to
-4 °F), petroleum 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 temper-
atures below 0 °C (32 °F), up to 60% petroleum can
be added (see diagram).
In most cases, adequate resistance to cold can also
be obtained by adding a fluidizing additive for winter
operation.
