Aircraft gas turbine engines use synthetic polyester fluids since they are formulated to handle a wide range of severe operating conditions. The factory supplied Spectroil M/N program for compliance to the JOAP program uses D19 and D12 standards which are prepared from a mineral oil hydrocarbon base stock. For applications which require improved accuracy for polyol ester based oils, the SpectrOil analyzer offers a new calibration program called POE8 TURBO with matrix-specific elemental standards.
A large municipality located in the northwestern United States operates a fleet of over 1,700 vehicles and over 3,000 pieces of motorized equipment which it uses for critical everyday functions. As you can imagine, maintenance on this equipment is expensive with oil changes alone costing in excess of $3 million dollars annually when done at set intervals. The municipality recognized that they could save millions of dollars by using oil analysis on their fleet to extend oil change intervals as well as identify and fix serious problems before they cause a catastrophic failure.
