UNUSUAL CONDITIONS
a. Service Intervals.
Increase frequency of lubricating servce intervals when
operating under unusual conditions such as high or low temperatures, prolonged
high-speed driving, deep mud, and extended cross-county operations. Such
operations can destroy a lubricant’s protective qualities. More frequent lubricating
service intervals are necessary to maintain vehicle readiness when operating in
unusual conditions. During inactive periods, with adequate preservation, service
intervals can be extended.
b. Changing Lubricant Grade.
Lubricant grade used varies with weather
conditions. Refer to table 1-12 for lubricant grade changes for the following
temperature ranges:
(1)
+l5°F (-10°C) and above
(2)
+40°F to -15°F (+5°C to -25°C)
(3)
+40°F to -65°F (+5°C to -55°C)
(4)
Arctic conditions: Refer to FM 9-207

LO 9-2320-209-12-1. Steps must be taken to replenish and maintain operating
levels.
