4 Fuel, Oils, Coolant
4.1 Diesel fuels
The composition of the fuel is vital for operation of the engine, its service life, and emissions. To meet
the performance specified and to run your boat cleanly and quietly, it is vital that you use fuel as rec-
ommended below:
Fuel specifications
The fuel must be approved according to national and international standards for commercial fuels, for
example:
– EN 590 (With environmental and sub-zero temperature specifications according to national require-
ments)
– ASTM-D975 No. 1-D and 2-D
– JIS KK 2204
Sulfur content: According to current legislation in the respective country.
Note. Large variations occur in merchant fuel specifications which have influence on engine power
output and fuel consumption.
Declared power is measured with fuel acc. to ISO 3046 with a lower calorific value of 42.700 kJ/kg
and a density of 840 g/liter at +15
o
C (59
o
F).
4.2 Lubricating oil, engine
A lubricating oil of a grade in accordance with the table below should be used:
Designation Standard
VDS, VDS-2* VDS* Volvo Drain Specification
CD,CE API (American Petroleum Institute)
MIL-L-2104D US Government’s Military Spec.
* A VDS oil must be used if there is to be a long period between oil changes. See also the maintenance schedule in chap. 6.3 and
“Technical Data” chap. 13.
We do not advise that you run on an oil of a grade which does not meet the above requirements. This
is a poor solution with respect to both economy and operating safety.
For viscosity and capacities, see “Technical Data” in chap. 13.
