4.2 - ENGINE OIL
The correct SAE viscosity grade of oil is determined by the minimum ambient temperature during cold
engine start-up, and the maximum ambient temperature during engine operation.
Refer to Table "Engine Oil Viscosity" (minimum temperature) in order to determine the required oil
viscosity for starting a cold engine.
Refer to Table "Engine oil Viscosity" (maximum temperature) in order to select the oil viscosity for
engine operation at the highest ambient temperature that is anticipated.
Generally, use the highest viscosity oil that is available to meet the requirement for the temperature at
start-up.

(If the engine oil is used with a high sulfur level, change the engine oil at shorter
intervals, approximately half)
