Phillips 66 Aviation Anti-Rust Oil 20W-50
Overview
|
Phillips 66 Aviation Antirust Oil is a rust preventive oil specially formulated to help protect aircraft piston engines against rust and corrosion during extended periods of inactivity. Airframe manufacturers have used it for many years as “Fly Away Oil” for new or rebuilt aircraft engines that are expected to sit idle for extended periods of time. Aviation 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. When preparing an aircraft for storage, drain the used engine oil and refill with Aviation Antirust Oil. Start the engine and warm it up to normal operating temperature to ensure that the new oil is fully circulated throughout the engine and allowed to coat all engine parts. For best results, fly the aircraft prior to storage. Covering exhaust and intake ports is recommended to minimize exposure to moisture during storage. Aviation Antirust 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. When returning the plane back to normal operation after storage, this oil should be replaced with regular operational engine oil such as Phillips 66 X/C® 20W-50 Aviation Oil. Aviation Antirust Oil is compatible with our other aviation engine oils, and may be used as a “supplement” to those products to enhance rust and corrosion protection when used in infrequently flown aircraft, particularly where high humidity is a concern. When used as a supplement, we recommend replacing up to 10% of the crankcase volume with Aviation Antirust Oil in place of the normal operational engine oil. |

I really appreciate Phillips and Aircraft Spruce for packaging and pricing this oil such that its economical for a person only needing to store one engine. The Aeroshell alternative is far too expensive (5 gallons minimum size of concentrate) and too large.

Works as advertised so far. Good product for low use engines. Non-dispersant base. Lots of engines have gone to TBO on straight mineral oil.

Per the tech data sheet posted in the Documents Tab on this web page, you can use up to 10% of the crankcase volume with the normal operating oil. We would suggest consulting with your A&P mechanic or Phillips Oil directly for more details on your specific application. There is a technical hotline phone number in the document.
This is more of storage oil. If you are flying once every couple of weeks this would not be recommended. If the plane is sitting months on end then it may be an option.
