Phillips 66 - 20W-50 Aircraft Piston Engine Rust & Corrosion Preventive Oil - Gallon Jug | 104910

Phillips 66® Aviation Anti-Rust 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 sit idle for extended periods. You can use Phillips Aviation Antirust Oil as "break-in oil." where an all-mineral oil is desired and is particularly suited for situations where the engine needs to be broke in and may not be immediately put into normal operating service.

When preparing an aircraft for storage, drain the used engine oil and refill it with
Aviation Anti-Rust Oil. Start the engine and warm it up to the average 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 before storage. Covering exhaust and intake ports is recommended to minimize exposure to moisture during storage.

Aviation Anti-Rust Oil is not designed to be an everyday operational engine oil in
aircraft flown frequently. It does not contain ashless dispersant additives. The operation time on this oil should not exceed 10 hours. When returning the plane 
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 Anti-Rust 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, exceptionally 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 standard operational engine oil.
