Engine Oil and Filter - Change
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.
Engine Oil and Filter - Change
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
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.
