Stationary back-up power generator. It was exercised at no-load once per week for 30 minutes. Had to run the facility once during this OCI for an hour or two, about a year and a half before the sample. Filters are as old as the oil. Now that I'm here, we're modifying our maintenance practices on this engine. 604.5 hours on the engine at sample time. Engine is ~20 years old.
