AeroShell Turbine Oil 555
Aviation Synthetic Turbine Oil Helicopter transmission, Heli synthetic gearbox oil, DOD-PRF-85734A, XAS-2354, DOD-L-85734, OX-26, O-160,
Synthetic lubricating oil for aircraft turbine engines, More recently with the need to transmit more power and higher loads through helicopter transmission and gearbox systems (many helicopters use a synthetic turbine engine oil in the transmission/gearbox system) it has become apparent that the use of a very good load carrying oil,
AeroShell Turbine Oil 555 is also approved for use in the industrial and marine versions of the Rolls-Royce RB211-22 and Olympus engines, General Electric LM 100, 250, 350, 1500 and 2500 engines.
High temperatures and load carrying requirements of SST engines and the DEF STAN 91-100 (formerly DERD 2497) and XAS-2354 specifications. AeroShell Turbine Oil 555 was also designed to give enhanced performance in current engines.
DOD-L-85734, which covers a helicopter transmission oil against which AeroShell Turbine Oil 555 is fully approved
AeroShell Turbine Oil 555 contains a synthetic ester oil and should not be used in contact with incompatible seal materials and it also affects some paints and plastics.
