|  | AeroShell Turbine Oil 555 Synthetic Turbine Engine OilWith such a hard life and all the daily stresses, what's a poor little aircraft turbine engine to do? Fortunately for your aviation engine, there's AeroShell Turbine Oil 555 synthetic turbine engine oil. This superior Shell turbine oil protects gas turbine engines from everyday wear and tear, corrosion and other serious damage. When your aircraft engine is under less stress, so are you!
AeroShell 555 is made from hindered polyol esters for exceptional stability over a wide range of operating temperatures. Its advanced additives formula improves load-carrying capabilities, which enhances the high level of protection. This turbine oil conforms to various specifications, such as DOD-L-85734, from the Department of Defense. See applications, features and specifications for detailed information.
See the AeroShell 555 MSDS for safety information.
Approvals/References/Specification

- General Electric Specification: D-50 TF 1
- Joint Service Designation Specification: OX-26
- NATO Specification: O-160

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, 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
