Aeroshell - Turbine Oil 555, PRF-85734A, Quart| 550042551_EACH

AeroShell Turbine Oil 555 is an advanced 5 mm2/s synthetic hindered ester oilincorporating a finely balanced blend of additives to improve thermal and oxidation stabilityand to increase the load carrying ability of the base oil.

APPLICATIONS:
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 (formerly DERD
2497) and XAS-2354 specifications. AeroShell Turbine Oil 555 was also designed to give
enhanced performance in current 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, 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 (now DOD-PRF-85734A),
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. Refer to the
General Notes at the front of this section for further information.
