CauTion
API Cd, API Ce, API CF-4 or MIl-
l-2104C/d/e oils can inhibit the
running-in process in new or
reconditioned engines and are not
suitable for engines running on low-
duty cycles.
4.2 oil visCosiTy
The chart
(Figure 4.2)
shows the
recommended oil viscosity ranges for
various ambient temperatures from
cold-start to maximum running.
In order to maintain the cold starting
characteristics of any recommended
grade it is essential that oil changes
are made within the Lister Petter
recommendations.
An oil change is recommended
immediately if the engine fails to reach
its normal cold start cranking speed
due to excessive oil viscosity.
CauTion
do not allow the lubricating oil to
become contaminated with fuel
as this will adversely affect cold-
starting and oil consumption.
SAE 30 and 10W-30 oils may be
used at up to 52°C (126°F), but oil
consumption may be affected. 10W-40,
15W-40 and 20W-40 multigrades are
recommended for continuous full-load
operation at this temperature.
Monograde SAE 40 oils are not
recommended.
4.3 Fuel speCiFiCaTion
The fuel used in your engine must be
diesel fuel oil which conforms to one of
the following:
• BS 2869: 1988 Class A2
• BS EN590: 1995 Class A1
• USA Specification ASTM D-975-77
Grades No. 1-D and 2-D
• BSMA 100 Class M1 for marine
use
The fuel must be a distillate and not a
residual oil or blend. Vaporising oils are
not suitable as fuels for these diesel
engines.
CauTion
do not attempt to operate the
engine on fuels outside the above
specifications, as this may result in
excessive wear and a loss in engine
performance.
The fuel injection equipment is
manufactured to very accurate limits,
and the smallest particle of dirt will
destroy its efficiency.
WarninG
It is essential to ensure that the
fuel is kept free from water and
contaminants.
4.4 loW TemperaTure
Fuels
Special winter fuels are often available
for use at ambient temperatures below
0°C (32°F).
These fuels have a lower viscosity
and limit the formation of wax at low
ambient temperatures.
CauTion
Wax formation can rapidly reduce
the flow of fuel through the fuel filter
element.
