In addition to the possibilities listed in paragraph 2.3.3.1 and 2.3.3.2, it is recommended that SAE
15W-40 (item 1, appendix E) be used when average ambient temperatures are 32 °F ( 0 °C), and
SAE 5W-30 (item 2, appendix E) when average temperatures are 32 °F ( 0 °C).
2.3.3.3 Oil Change Intervals.
Since oil deterioration depends on operating conditions, fuel quality, and oil quality, oil change intervals
can vary. Table 2-6 indicates oil change intervals in operating hours (OH). Factors affecting these intervals
include:
l Oil quality
l
Sulfur content of the diesel fuel
l
Outside temperature (daily average)
NOTE
Use HOURMETER to determine operating hours.
