Our turbine oil is already in its critical warning limit in terms RPVOT values and we are planning to sweeten up or adding anti-oxidants package as stop gap measure as per recommendation of our oil supplier, since we can't afford to a sudden outage since its not our scheduled maintenance. Also the oil is already 5 years in service and we observe some thick foaming of oil. Would appreciate If could get some sweetening procedure on turbine oils in general?
