Turbine engine oils (abbreviated as TEOs), also known as jet oils, turbo oils are specialty lubricants designed to support the operation of turbine engines. Apart from their lubricating function of the engine, gearbox, shafts and associated accessories, TEOs have two additional functions. Their various additives protect the components from corrosion, and filter contaminants in the engine such as carbon deposits (coking) while TEOs are also used as heat transfer fluids, cooling the engine in temperatures reaching 1000°C, in turn extending the life of the oil up to 25,000 hours of operation. TEOs have been initially developed as mineral and and subsequently innovated to synthetic.
TOTALENERGIES (formerly TOTAL) Specialties has developed a comprehensive turbine lubricant product range to support the power generation industry (whether it’s for large frame or aero-derivative turbines) with approvals by the leading turbine manufacturers. Offered in 20-liter containers and drums of 208 liters (210 kg) each.
TOTALENERGIES PRESLIA range of turbine oils include:
a) PRESLIA mineral high-performance turbine lubricants for regulation and lubrication circuits of gas, steam and combined cycle turbines working at high temperatures. Can also be used in centrifugal and screw compressor bearing lubrication when an oil without strong anti-wear properties is needed. These oils offer long drain intervals, simplified maintenance and ageing protection of engines and equipment in which they are used. Key features include:
- High oxidation resistance, antifoam, air and water release performances.
- High antiwear properties allowing the lubrication of the gear boxes driven by the turbine.
- High antirust and anticorrosion performances.
- Important « hydraulic properties » especially hydrolysis stability and filterability (with or without water).

b) PRESLIA GT (ISO 32 and 46) high-running temperature resistant turbine lubricants. These oils are specially designed for the lubrication (bearing, gear boxes) and regulation of gas turbines. The use of non-conventional base stocks and unique additization provides excellent thermal-oxidative stability. Preslia GT 32 and 46 should also be considered for use in steam turbine applications that requires aither an ISO 32 or 46 fluid.
