Refill Capacities
Refer to Table 19 (minimum temperature) in order
to determine the required oil viscosity for starting a
cold engine.
Refer to Table 19 (maximum temperature) in order
to select the oil viscosity for engine operation at the
highest ambient temperature that is anticipated.
Generally, use the highest oil viscosity that is
available to meet the requirement for the temperature
at start-up.

Synthetic Base Stock Oils
Synthetic base oils are acceptable for use in
these engines if these oils meet the performance
requirements that are specified for the engine.
Synthetic base oils generally perform better than
conventional oils in the following two areas:
•
Synthetic base oils have improved flow at low
temperatures especially in arctic conditions.
•
Synthetic base oils have improved oxidation
stability especially at high operating temperatures.
Some synthetic base oils have performance
characteristics that enhance the service life of the
oil. Perkins does not recommend the automatic
extending of the oil change intervals for any type of
oil.

Re-refined Base Stock Oils
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 oils can be used
exclusively in finished oil or in a combination with
new base stock oils. 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.
