Aeroshell Turbine Oil 500 is a 5 mm^2/s synthetic hindered ester oil incorporating a carefully selected and balanced combination of additives to improve the thermal and oxidation stability and metal passivation. 

Key Features:

• Developed to meet 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 is also affects some paints and plastics
