AeroShell Turbine Engine Oil 500 Synthetic Lubricating Oil For Gas Turbine Engines

Synthetic lubricating oil for aircraft turbine engines

Aeroshell Turbine Oil 500 is a 5 mm2 /s synthetic hindered ester oil incorporating a carefully selected and balanced combination of additives to improve thermal and oxidation stability and metal passivation.

ASTO 500 may help to keep engine components clean, thereby extending bearing life and reducing maintenance costs. It is a 5-cSt, hindered-ester synthetic oil with carefully selected and balanced additives, and has been developed to meet the MIL-PRF-23699 (STD) specification. ASTO 500 has good corrosion and oxidation stability, which can help to protect engines and cut costs.

ASTO 500 is fully approved to:

• MIL-PRF-23699G standard grade
• SAE AS 5780B SPC
• DEF STAN 91-101 Grade OX-27

Aeroshell Turbine Oil 500 was developed essentially to meet the requirements of Pratt & Whitney 521 Type II and MIL-L-23699 specifications and is entirely suitable for most civil and military engines requiring this class of lubricant. Aeroshell Turbine Oil 500 is approved for use in a wide range of turbine engines as well as the majority of accessories.

With the advent of the new civil turbine oil specification, SAE AS5780, which has more stringent requirements than the military specification MIL-PRF-23699, Aeroshell Turbine Oil 500 was approved as a SPC (Standard Performance Capability) oil. Aeroshell Turbine Oil 500 contains a synthetic ester oil and should not be used in contact with incompatible seal materials and it also affects some paints and plastics.
