RECLAIMING OF DETERIORATED SPECIFICATION MIL-L-7808 AIRCRAFT GAS TURBINE OILS

Abstract

Samples representative of 35,000 gallons of MIL-L-7808 oil which had deteriorated during storage were examined. All contained insoluble matter and two were corrosive to lead. Methods of reclaiming these oils with adsorbents were investigated; only a chromatographic grade alumina efficiently removed the lead-corrosive component. The antioxidant and antifoam agents were not removed by this process, since the treated oil successfully passed the pertinent tests. It is estimated the deteriorated oil may be reclaimed for approximately 20 percent of its current replacement cost. This figure is based on materials cost and losses during processing; it does not include handling and packaging charges. A treatment process is recommended.
