There are no industry standard tests that evaluate
the performance or the compatibility of aftermarket
additives in finished oil. Aftermarket additives may
not be compatible with the finished oils additive
package, which could lower the performance of the
finished oil. The aftermarket additive could fail to mix
with the finished oil. This failure could produce sludge
in the crankcase. Perkins discourages the use of
aftermarket additives in finished oils.
To achieve the best performance from a Perkins
engine, conform to the following guidelines:
• See the appropriate "Lubricant Viscosities". Refer
to the illustration 42 to find the correct oil viscosity
grade for your engine.
• At the specified interval, service the engine. Use
new oil and install a new oil filter.
• Perform maintenance at the intervals that are
specified in the Operation and Maintenance
Manual, "Maintenance Interval Schedule".
Oil analysis
Some engines may be equipped with an oil sampling
valve. If oil analysis is required, the oil sampling valve
is used to obtain samples of the engine oil. The oil
analysis will complement the preventive maintenance
program.
Note: Ensure that there is sufficient quantity of oil in
the engine before taking a sample of oil with the
engine in operation. The engine oil capacity must not
go below the minimum quantity specified on the oil
level gauge. Refer to this Operation and Maintenance
Manual, "Engine Oil Level - Check" for the correct
procedure.
The oil analysis is a diagnostic tool that is used to
determine oil performance and component wear
rates. Contamination can be identified and measured
by using oil analysis. The oil analysis includes the
following tests:
• The Wear Rate Analysis monitors the wear of the
engines metals. The amount of wear metal and
type of wear metal that is in the oil is analyzed.
The increase in the rate of engine wear metal in
the oil is as important as the quantity of engine
wear metal in the oil.
• Tests are conducted to detect contamination of the
oil by water, glycol, or fuel.

• The Oil Condition Analysis determines the loss of
the oils lubricating properties. An infrared analysis
is used to compare the properties of new oil to the
properties of the used oil sample. This analysis
allows technicians to determine the amount of
deterioration of the oil during use. This analysis
also allows technicians to verify the performance
of the oil according to the specification during the
entire oil change interval.
