The engine accumulated 30,312 hours and 15,080 cycles since new and was removed for scheduled performance restoration and core section life-limited parts (LLP) replacement.

Considering the extraordinarily high time on the engine and its 2:1 hour/cycle ratio usage, the engine oil system was exceptionally clean and free of oil-derived deposits.
