Refill Capacities
Refer to Table 1
9 (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 ambi
ent 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-refinedbasestockoilscanbeused
exclusively
in finished oil or in a combination with
new base stock oils. The US military specifications
and the specifications of other heavy equipment
manufacture
rs also allow the use of re-refined base
stock oils that meet the same criteria.
The process t
hatisusedtomakere-refined base
stock oil should adequately remove all wear metals
that are in the used oil and all the additives that
areintheus
ed 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. Fi
ltering is adequate for the production of
high quality, re-refined base stock oil.
Lubricant
s 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 flowinginlow
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 stoc
k multigrade oil with an 0W viscosity grade
orwitha5Wviscositygrade.Useanoilwithapour
point that is lower than −50 °C (−58 °F).
The number of acceptable lubricants is limited in
cold weather conditions. Perkins recommends the
followi
ng lubricants for use in cold weather conditions:
First Choice – Use oil with an EMA DHD-1
Recomme
nded 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
lubrica
nt viscosity grade.
Second Choice – Use an oil that has a CH-4
additi
ve 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 5W3
0, or SAE 5W40.
NOTICE
Shortened engine service life could result if second
choice oils are used.
