AeroShell 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 increase the base oil's load-carrying ability.
APPLICATIONS: AeroShell Turbine Oil 555 was specifically developed to meet SST engines' high temperatures and load-carrying requirements and the DEF STAN 91-100 (formerly DERD 2497) and XAS-2354 specifications. AeroShell Turbine Oil 555 was also designed to enhance current engines' performance.
More recently, with the need to transmit more power and higher loads through helicopter transmission and gearbox systems (many helicopters use synthetic turbine engine oil in the transmission/gearbox system), it has become apparent that the use of a perfect load-carrying oil, such as AeroShell Turbine Oil 555 is necessary. This 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 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.
I normally wear an xl for 95% of my shirts. I ordered a 2XL in this just to be safe. STILL too small. Sizing is crazy. You can do better. Charge me for a correctly sized shirt, I don’t care! But don’t do this.
I’m NOT taking a pic.
