Engine Oil Specification
• 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 or Fluid
Recommendations Fuel Specification".
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.
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.
For more information on wear metals, refer to
Specifications, "Engine Oil Filter (Extended Oil
Service)" or consult your Perkins distributor.
• 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.

diesel engines, contact your Perkins distributor.
