Phillips 66 Anti-Rust Aviation Engine Oil 20w-50 is a rust and corrosion preventive oil for aircraft piston engines that is specially formulated to help protect against rust and corrosion during extended periods of inactivity.
Airframe manufacturers also use it as a “Fly Away Oil” for new or rebuilt aircraft engines that are expected to sit idle for extended periods of time. Antirust oil may be used as “break-in oil” where an all-mineral oil is desired, and is particularly suited for situations where the engine to be broken in may not be immediately put into regular service.
This oil is not designed to be an everyday operational engine oil in aircraft that are flown frequently. It does not contain ashless dispersant additives. Operation time on this oil should not exceed 10 hours.
Meets the requirements of:
SAE Standard J1966
U.S. Military Specification MIL-C-6529C
U.S. Military Specification MIL-L-6082E (Base Oil) (obsolete)
