Oil analysis revealed severe contamination and wear. Iron particle count was 785 (target 25 or less), with a high PQ index indicating significant ferrous debris. Viscosity measured at 265 cSt versus the expected 320 cSt for AGMA 6 oil. Water content had doubled since the previous sample, and changes in the additive package indicated the lubricant was not consistent with prior oil used.

The CME recommended verifying the correct lubricant was in use and performing a hot oil flush to remove contamination and wear metals. If flushing was not feasible, a full oil change was advised along with installing a filtration system using a 7-micron beta 1000 filter.

The customer replaced the oil with the correct specification. This action restored proper lubrication conditions and prevented an estimated 336 hours of unplanned downtime.
