SGE324 Aeroshell Turbine Oil 555 – Case 24 x 1 USQ (DEF STAN 91-100 OX-26)

Aeroshell Turbine Oil 555 – Case 24 x 1 USQ (DEF STAN 91-100 OX-26) - Aeroshell

Product description:

AeroShell Turbine Oil 555 was specifically developed to meet the high temperatures and load carrying requirements of SST engines and the DEF STAN 91-100 & XAS-2354. Turbine Oil 555 was also designed to enhance performance in current engines.


Turbine Oil 555 is an advanced 5 mm2/s synthetic hindered ester oil incorporating a finely balanced blend of additives to improve thermal and oxidation stability and to increase the load carrying ability of the base oil. With the need to transmit more power and higher loads through helicopter transmission and gearbox systems it has become apparent that the use of a very good load carrying oil, such as AeroShell Turbine Oil 555 is necessary. This in turn has led to the development of a U.S. Military Specification, DOD-L-85734 which covers a helicopter transmission oil against which Turbine Oil 555 is fully approved.
