Diesel Engine
Oil Performance Recommendations
CC/SF for use in naturally aspirated engines and in engines
that operate in light duty service including standby and
emergency operation (equivalent to MIL-L-2104B).
Sulfated Ash Limit of 1.85% by weight is recommended.
Oils with higher ash count may produce deposits on valves
that can progress to guttering and valve burning.
Do not use “break-in” lubricating oils in new or rebuilt
engines. Use lubricating oils specified for normal engine
operation.
Oil Viscosity Recommendations
The use of a multigrade lubricating oil improves oil
consumption control and improves engine cranking in cold
temperatures while maintaining lubrication at high operating
temperatures. A multigrade oil is therefore recommended
with the viscosity grades shown in the following chart. The
use of single grade lubricating oils is not recommended,
except for synthetic oils used in Arctic conditions.
Viscosity Grades
Arctic Operation
NOTE: SAE 5W viscosity grade synthetic oil may be used
when operating the engine in ambient
temperatures below -10° F (-23° C) provided they
meet the minimum viscosity at 212° F (100° C).
When there is no provision to keep the engine warm when
operating in ambient temperatures consistently below -10° F
(-23° C), use a lubricating oil that meets the following
requirements:
Hoist gearbox 1-1/2-2 qts. (1.4-1.9 liters) SAE 90 EP gear lubricant or equivalent
Hoist brake 1/2-1 pt. (.2-.5 liters) SAE 20-20 motor oil
Swing gear pinion As required Open gear lube
