naturally aspirated, turbocharged or supercharged.
Oils designated for this service have been in existence since
1994 and may be used when API Service Category CD is
recommended.
API Service Category CF-2:
Severe duty, two-stroke cycle Service typical of two-stroke cycle
diesel engines requiring highly effective control over cylinder
and ring-face scuffing and deposits.
Oils designed for this service have been in existence since 1994
and may also be used when API Engine Service Category CD-11
is recommended.
These oils do not necessarily meet the requirements of API
CF or CF-4 unless they pass the test requirements for these
categories.
API Service Category CG-4 - 1994:
Severe duty
API Service Category CG-4 describes oils for use in high-speed
four-stroke-cycle diesel engines used in both heavy-duty on-
highway (0.05% weight sulphur fuel) and off-highway (less than
0.5% weight sulphur fuel) applications.
CG-4 oils provide effective control over high-temperature piston
deposits, wear, corrosion, foaming, oxidation stability, and soot
accumulation.
These oils are especially effective in engines designed to meet
1994 exhaust emission standards and may also be used in
engines requiring API Service Categories CD, CE, and CF-4.
Oils designed for this service have been in existence since
1994.
The Oil Specification
To help assist engine running-in, all engines are despatched
with an initial fill lubricating oil which must be changed after
100 hours.
1. The temperatures mentioned in the table are the ambient
temperatures at the time when the engine is started. However,
if monograde oils are used and running ambient temperatures
are significantly higher than starting temperatures, a higher
viscosity oil should be selected subject to satisfactory starting
performance. Multigrade oils may be used to overcome the
problem.
2. Where it is not practical to continually change oils to suit
varying ambient temperatures a suitable multigrade oil is
recommended to ensure adequate starting performance at
the lowest temperature likely to be encountered.
3. The engines must be run on heavy duty lubricating oils.
Straight mineral oils are not suitable, neither are oils of less
detergency than specified.
4. API CF-4, API CG-4, API CH or API CI oils are recommended
for heavy duty load applications, with API CC or API CD for
light duty load applications.
5. For engines in long running installations Lister Petter Power
Systems should be consulted.
CAPTION
Lister Petter Power Systems recommend that oils
of different brands or types are not mixed together.

API Service Category CF:
Indirect injection
Service typical of indirect-injected diesel engines
and other diesel engines that use a broad range
of fuel types, including those using fuel with high
sulphur content; for example, over 0.5% weight.
Effective control of piston deposits, wear and
copper-containing bearing corrosion is essential for
these engines, which may be naturally aspirated,
turbocharged or supercharged.
Oils designated for this service have been in
existence since 1994 and may be used when API
Service Category CD is recommended.
API Service Category CF-2:
Severe duty, two-stroke cycle

requiring highly effective control over cylinder and
ring-face scuf fing and deposits.
Oils designed for this service have been in existence

Service Category CD-11 is recommended.
These oils do not necessarily meet the requirements
of API CF or CF-4 unless they pass the test

API Service Category CG-4 describes oils for use in

CAUTION
Oil Viscosity
Notes:
A. Intermittent running.
B. Synthetic oils only.
°F = (1.8 x °C) + 32.
1.SAE 5W-20 oils are recommended on the
basis that they are fully synthetic, and are
technically suitable for use up to 25°C (77°F).
Non synthetic oils at very low temperatures
will suffer from wax crystallisation.
Monograde SAE 5W is not normally available as
a synthetic oil and therefore is not quoted.
An oil change is recommended immediately
if the engine fails to reach its normal cold
start cranking speed due to excessive oil
viscosity.
Lister Petter Power Systems recommend that oils
of different brands or types are not mixed together.
2. In order to maintain the cold starting
characteristics of any recommended grade
it is essential that oil changes are made
within the Lister Petter Power Systems
recommendations.

Fuel dilution of the lubricating oil will adversely affect cold starting and oil consump-
tion.
3.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.
4 .Monograde SAE 40 oils are not recommended.
3.2 Engine Fluids - Fuel
The Fuel Specification
The engine must only be used with diesel fuel oil which
conforms to one of the following:
a. BS 2869:1988 Class A2.
b. BS EN590:1995 Class A1.
c. USA Specification ASTM D-975-77 Grades No.1-D and 2-D.
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 Lister Petter Power
Systems engines.
The user is cautioned that although the engines may operate
on fuels outside the above specifications, such operation may
well result in excessive wear and damage.
