LUBRICATING OIL
3.1.1 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.
The lubricating oil specification is given in the
Operators Handbook and care must be taken to
ensure the correct handbook is being referred to:
LPW, LPWT, LPWS(T) .................P027-08270
CAUTION
Lister Petter Power Systems recommend that
oils of different brands or types are not mixed
together.
3.1.2 European Oil Specifications
ACEA specifies the following:
Gasolene engines: A1-96, A2-96, A3-96.
Light duty diesel engine operation: B1-96, B2-96, B3-96.
Heavy duty and commercial vehicle diesel engine
operation: E1-96, E2-96, E3-96.
3.1.3 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.
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.
ALPHA SERIES ENGINES WORKSHOP MANUAL
3. ENGINE FLUIDS
An oil change is recommended immediately if
the engine fails to reach its normal cold start
cranking speed due to excessive oil viscosity.
Fuel dilution of the lubricating oil will adversely
affect cold starting and oil consumption.
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. M o n o g r a d e S A E 4 0 o i l s a r e n o t
recommended.
3.1.4 The Oil Classification System
The information contained in this section
has been extracted from "Lubricant and Fuel
Performance", with the permission of 'The
Lubrizol Corporation'.
Some of the following classifications may not
be available in your country. In cases of
difficulty, it is suggested contact be made with
a reputable oil supplier or any Lister Petter
Power Systems Distributor.
Past and Current US API Grade Oils
API Service Category CD:
Service typical of certain naturally aspirated,
turbocharged or supercharged diesel engines
where highly effective control of wear and deposits
is vital, or when using fuels with a wide quality
range (including high-sulphur fuels).
Oils designed for this service were introduced in
1955 and provide protection from high temperature
deposits and bearing corrosion in these diesel
engines.
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.
