3.0/5 rating (2 votes)


AeroShell Turbine Oil 560 (ASTO 560) is a third generation, high performance, low coking 5 mm2/s synthetic hindered ester oil incorporating a carefully selected and balanced combination of additives to improve thermal and oxidation stability.

AeroShell Turbine Oil 560 (ASTO 560) was developed to withstand the hostile environment of today’s high powered, high compression engines in which the older generation of oil can be stressed up to and beyond their thermal limits, as evidenced by oil coking in the high temperature bearing area.


In order for military authorities to take advantage of this better performance in military engines the specification MIL-PRF-23699 was re-written to include “High Thermal Stability” (HTS) grade as well as the standard (STD) and Corrosion Inhabited (C/I) grades. AeroShell Turbine Oil 560 (ASTO 560) is fully approved as as HTS oil. With the advent of the new civil turbine oil specification, SAE AS5780, which has more stringent requirements than the military specification, AeroShell Turbine Oil was approved as a SPC (Standard Performance Capability) oil.
