Lubricant Viscosities
Supplemental heat is recommended for cold soake d starts below
the m inimum am bient temperature. S upplemental heat m ay be
required for cold soaked starts that ar e above the minimum
temperature that is stated, depending on the pa rasitic load and
other factors. Cold soaked starts occur when the engine has not
been operated for a period of time. T his interval will allow the oil to
become more v iscous due to cooler am bient temperatures.
Aftermarket Oil Additives
Perkins does not recommend the use of aftermarket
additives in oil. It is not necessary to use aftermarket
additives in order to achieve the engines maximum
service life or rated performance. 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. 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
totheillustration43inordertofind 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 mainte
nance at the intervals that are
specified in the Operation and Maintenance
Manual, “Maintenance Interval Schedule”.
Oil analysis
Some engines
maybeequippedwithanoilsampling
valve. If oil analysis is required, the oil sampling valve
is used to obtain samples of the engine oil. The oil
analysis wi
ll complement the preventive maintenance
program.
The oil anal
ysis is a diagnostic tool that is used to
determine oil performance and component wear
rates. Contamination can be identified and measured
by using oi
l analysis. The oil analysis includes the
following tests:
•
The Wear Ra
te 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 in order 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
deteri
oration of the oil during use. This analysis
also allows technicians to verify the performance
of the oil according to the specification during the
entir
e oil change interval.
