ROYCO® 482 MIL-C-6529C2, Type II Spec Corrosion Preventative Oil - 5 Gallon Pail

ROYCO 482 is a light green rust and corrosion preventative oil commonly used to preserve aircraft internal combustion engines.

Formulated with highly refined petroleum base oils and an ashless anti-corrosion additive package, ROYCO 482 protects the engine by minimising the effects of humidity and neutralising the acidic components of engine oil oxidation and combustion by-products. It is primarily used as a preservation grade engine oil for internal protection of engines or engine parts and accessories during moderate outdoor to long term indoor storage periods. ROYCO 482 may also serve as a "flyaway" oil for reciprocating engines, though operation with the diluted material should not exceed 50 hours before an oil change. For preservation, the engine should be filled to normal capacity with ROYCO 482 and then run at idle until reaching operating temperature (approx. 10 - 15 minutes). Upon shutdown the internal surfaces of the engine are now protected for lasting rust and corrosion protection.
