Recommended Oil Change Intervals
Table 5-1
should only be used as an approximate
guide. For best results, an oil sampling program is
recommended.
The initial oil change should occur after the first
200 hours of operation. Thereafter, frequency of oil
changes will depend on the operating conditions.
Check for oil contamination periodically. Time
between oil changes should never exceed six (6)
months.
