Re refined base stock oil
Re refined base stock oils are acceptable for use in
Perkins engines if these oils meet the performance
requirements that are specified by Perkins .Re
refined base stock oil can be used exclusively in
finished oil or in a combination with new base stock
oil . The US military specifications and the
specifications of other heavy equipment
manufacturers also allow the use of re refined base
stock oils that meet the same criteria.
The process that is used to make re refined base
stock oil should adequately remove all wear metals
that are in the used oil and all the additives that are in
the used oil. The process that is used to make re
refined base stock oil generally involves the process
of vacuum distillation and hydrotreating the used oil.
Filtering is adequate for the production of high quality,
re refined base stock oil.
Lubricants for Cold Weather
When an engine is started and an engine is operated
in ambient temperatures below −20 °C (−4 °F), use
multigrade oils that are capable of flowing in low
temperatures.
These oils have lubricant viscosity grades of SAE 0W
or SAE 5W.
When an engine is started and operated in ambient
temperatures below −30 °C (−22 °F), use a synthetic
base stock multigrade oil with an 0W viscosity grade
or with a 5W viscosity grade. Use an oil with a pour
point that is lower than −50 °C (−58 °F).
The number of acceptable lubricants is limited in cold-
weather conditions. Perkins recommends the
following lubricants for use in cold-weather
conditions:
First Choice – Use oil with an EMA DHD-1
Recommended Guideline. Use a CH-4 oil that has an
API license. The oil should be either SAE 0W20, SAE
0W30, SAE 0W40, SAE 5W30, or SAE 5W40
lubricant viscosity grade.
Second Choice – Use an oil that has a CH-4 additive
package. Although the oil has not been tested for the
requirements of the API license, the oil must be either
SAE 0W20, SAE 0W30, SAE 0W40, SAE 5W30, or
SAE 5W40.
NOTICE
Shortened engine service life could result if second
choice oils are used.
Aftermarket Oil Additives
Perkins does not recommend the use of aftermarket
additives in oil. The use aftermarket additives in order
to achieve the engines maximum service life, or rated
performance is not necessary. Fully formulated,
finished oils consist of base oils and of commercial
additive packages. These additive packages are
blended into the base oils at precise percentages in
order to help provide finished oils with performance
characteristics that meet industry standards.
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. An aftermarket additive 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:
• Select the correct oil, or a commercial oil that
meets the “EMA Recommended Guideline on
Diesel Engine Oil” or the recommended API
classification.
• See the appropriate “Lubricant Viscosities” table in
order 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.
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 the oil analysis. The oil analysis includes the
following tests:
