3.1 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.
All subsequent oil changes must be
as specified in "4.13 Maintenance -
schedule hours".
CAUTION
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 Distributor.
1. The temperatures mentioned in the
tables 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. ’L’ Series engines must be run on
heavy duty lubricating oils that at least
meet the requirements of one of the
following:
API CC
MIL-L-46152B
DEF2101D
MIL-L-2104B
Straight mineral oils are not suitable,
neither are oils of less detergency than
specified.
Note:
Higher specification oils meeting API CD,
API CE and API CF-4 are more commonly
available than API CC. The use of these
oils in new engines is acceptable for
topping up the 'first fill' and following the
first 100 hours when running-in has been
completed.
These oils are particularly suited to
engines running at a high load factor, or in
conjunction with high ambient
temperatures. They must also be used
where the sulphur content of the fuel
exceeds 0.5%.
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. The oil must be suitable for 250 hour
oil changes without undue degradation,
with sump temperatures reaching
150°C (302°F) under severe tropical
conditions, and 120°C (248°F) under
normal conditions.
5. For engines in long running
installations Lister Petter should be
consulted.
