Obtain
The
condition
of
the
engine
lubricating
oil
may
be
checked
at
regular
intervals
as
part
of
a
preventive
maintenance
program.
Perkins
include
an
oil
sampling
valve
as
an
option.
The
oil
sampling
valve
(if
equipped)
is
included
in
order
to
regularly
sample
the
engine
lubricating
oil.
The
oil
sampling
valve
is
positioned
on
the
oil
filter
head
or
the
oil
sampling
valve
is
positioned
on
the
cylinder
block.
Perkins
recommends
using
a
sampling
valve
in
order
to
obtain
oil
samples.
The
quality
and
the
consistency
of
the
samples
are
better
when
a
sampling
valve
is
used.
The
location
of
the
sampling
valve
allows
oil
that
is
flowing
under
pressure
to
be
obtained
during
normal
engine
operation.
Obtain
the
Sample
and
the
Analysis
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
In order to help obtain the most accurate analysis,
record the following information before an oil sample
is taken:
• The date of the sample
• Engine model
• Engine number
• Service hours on the engine
• The number of hours that have accumulated since
the last oil change
• The amount of oil that has been added since the
last oil change
Ensure that the container for the sample is clean and
dry. Also ensure that the container for the sample is
clearly labelled.
To ensure that the sample is representative of the oil
in the crankcase, obtain a warm, well mixed oil
sample.
To avoid contamination of the oil samples, the tools
and the supplies that are used for obtaining oil
samples must be clean.
The sample can be checked for the following: the
quality of the oil, the existence of any coolant in the
oil, the existence of any ferrous metal particles in the
oil and the existence of any nonferrous metal
particles in the oil.

Oil and Filter Change Intervals
The standard engine oil and filter change period is
500 hours. There are several other factors that can
alter the standard engine oil and filter change of 500
hours.
• If the engine is using engine oil analysis to
determine oil and filter change period.
• The engine is working in a severe service
environment/Load Factor
• Infrequent operation of the engine
Refer to this Operation and Maintenance Manual,
“Severe Service Application” for more information on
reducing the engine oil and filter change period. For
severe service applications the recommended oil and
filter change period is 250 hours.
If the engine is operated in severe service conditions,
Perkins recommends the use of engine oil sampling.
Refer to this Operation and Maintenance Manual,
Engine Oil sample - Obtain for more information.
If the engine is operated infrequently less than 500
hours in a 12-month period, then the engine oil and
filter change should be conducted yearly.
