Aeroshell Oil - Turbine Engine,QT, Aeroshell 560, PRF-23699F

In our industry, "low coking" has nothing to do with not stocking up on enough soft drinks. Any aviator who's earned his wings knows that it's all about temperature, oil residue and the stability of the lubricant.
AeroShell 560 Turbine Engine Oil is a low coking 5 centistoke synthetic hindered ester lubricant. it reduces deposits from high temperature conditions to improve engine performance because it's not made of mineral oil. Sometimes preventing sludge and varnish is not possible. No worries, with AeroShell 560 dissolving such gunk is part of its job description.
AeroShell 560 Turbine Engine Oil meets the standards expressed in MIL-PRF-23699-F, so it's highly suited for modern machinery. And it is widely known the U.S. military is always on the cutting edge of technology. By using this oil, you can be certain it is in line with the military's rigid regulations.
Further evidence can be found in standard load-carrying tests, where AeroShell 560 consistently achieves an 8 percent improvement over other MIL-L-23699 or DERD 2499 oils. As a savvy aviator looking for high performance oil well suited for the tough conditions of flight, you have arrived at the right destination: AeroShell 560.


  • Outstanding high temperature and oxidation stability.
  • High Viscosity Index Synthetic Base Fluids maintain viscosity and protect components.
  • Qualified to MIL-L-23699D, DERD 2499 grades OX-27 & OX-28 and NATO O-156 fluid [ A qualified product must be blended and packed in the plant listed on the QPL to ensure that the base oil is made in an approved refinery and that the product is blended and packed in an approved and closely monitored facility.] which provides compatibility with other similarly qualified oils.
