Turbine engine oils, sometimes referred to as jet oils, turbo oils or abbreviated to TEOs, are speciality lubricants designed to support the operation of turbine engines. First developed during the 1940’s, turbine engines can now be seen on almost all commercial aircraft currently in operation. While aviation is the main market place for these oils, there are other applications, especially in the power industry, where turbine engines are used.
Unlike piston engines, that convert an up and down movement from a piston into motion, turbine engines combine compressed air with the chemical reaction from the fuel within the engine to drive fan blades. This means that turbine engines reach much higher temperatures, and this has driven innovation in mineral TEOs, and subsequently synthetic TEOs.
