5°F (-15°C). For ambient temperatures
below 5°F (-15°C) SAE 5W-40 may be
used, provided it meets API CK-4 or CJ-4
oil specifications and biodiesel or biodiesel
blended fuel is not used as fuel for the
engine. Use of 0W-40 and 0W-30 synthetic
oils that meet API CK-4 or CJ-4
certification can be used in operations
where the ambient temperature never
exceeds 32°F (0°C). 0W-40 and 0W-30 oils
do not offer the same level of protection
against fuel dilution as do higher
multigrade oils. Higher cylinder wear can
be experienced when using 0W-40 or
0W-30 oils in high-load situations. Using a
multigrade oil helps improve engine
cranking in low-temperature conditions,
reduces deposit formation and increases
engine durability.
NOTE
For
severe duty
applications the use
of 15W-40 is advised.
CAUTION
The use of a fuel economy oil such as
an API FA-4 oil is not approved for this
engine. Failure to comply may result in
equipment or property damage.
Oil viscosity must be chosen according to
the typical climate conditions experiences
by the user. See the accompanying chart.
•
10W-30
is recommended for
normal engine operation and
provides the best wear protection.
•
15W-40
is compatible for improved
engine durability at extremely high
ambient temperatures.
•
5W-40
is approved for colder
ambient temperatures to improve
oil flow during start up.
•
0W-40
,
0W-30
synthetic oils that
meet CK-4 certification can be
used in operations where the
ambient temperature
never
exceeds 32°F (0°C). 0W-40 and
0W-30 oils do
not
offer the same
level of protection against fuel
dilution as do higher multigrade
oils. Higher cylinder wear can be
experienced when using 0W-40 or
0W-30 oils in high-load situations.

Any of the oil weights listed in the
chart above are acceptable to use as
long as the oil meets API CK-4/CJ-4
oil specifications.
New Engine Break-in Oils
PACCAR does not approve the use of
special “break-in” engine lubricating oils for
new or rebuilt PACCAR engines. It is
recommended to use the same lubricating
oil for engine break-in that will be used
during normal operation.
