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. Only 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 Figure 6-1. The use of
single grade lubricating oils is not recommended, except for
synthetic oils used in Arctic conditions.
Arctic Operation
NOTE: SAE 5W viscosity grade synthetic oil may be used

temperatures below -23°C (-10°F) provided it
meets the minimum viscosity at 100°C (212°F).
When there is no provision to keep the engine warm when
operating in ambient temperatures consistently below -23°C
(-10°F), use a lubricating oil that meets the following
requirements:
ENGINE COOLING SYSTEM
The engine cooling system consists of the coolant passages
in the engine, a thermostat, water pump, hoses and radiator.
The engine is cooled by the circulation of coolant through the
passages in the engine block and head. Circulation is by a
thermo-siphon action assisted by a water pump driven by a
belt from the crankshaft pulley.
The water pump bearings are packed with a special grease

Coolant Requirements
The quality of coolant will determine the efficiency and life of
the cooling system.

before the beginning of the cold season or hot season.

U.S.A. - Engineering Standard GM6038-M.

sodium nitrate inhibitors.
Australia - AS 2108-1977: Antifreeze compounds and
corrosive inhibitors for engine cooling systems.
2. There is an advantage to using antifreeze even when
frost protection is not necessary. Antifreeze protects
against corrosion and also raises the boiling point of the
coolant. A 50% concentration of antifreeze is preferred,
but if this much protection is not preferred, a 33%
concentration can be used. Never use more than a 65%
concentration under any conditions. Where frost
