CORROSION PREVENTATIVE COMPOUND
FOR RECIPROCATING AIRCRAFT ENGINES

GENERAL INFORMATION:
ROYCO 482 is a light green rust and corrosion preventative oil commonly used to preserve aircraft internal combustion engines. The ashless anti corrosion additive package and highly refined petroleum base oils protect
the engine by minimizing the effects of humidity and neutralizing the acidic components of engine oil oxidation and combustion by-products. ROYCO 482 is designated a preservative under MIL-STD-2073-1C.

APPLICATIONS:
ROYCO 482 is normally used as a preservation grade engine oil for the internal preservation of engines or engine parts and accessories during moderate outdoor to long term indoor storage periods. This oil can also be
used as a "flyaway" oil for reciprocating engines however operation of engines preserved with the diluted material should be limited to a maximum of fifty hours before oil change. The engine to be preserved should be filled to normal capacity with ROYCO 482 and then run at idle until the engine reaches normal operating temperature (approx. 10 - 15 minutes.) Upon shutdown the internal surfaces of the engine are now protected from rust and corrosion.

ADVANTAGES:
• Excellent thermal and oxidative stability
• Offers outstanding rust and corrosion protection

COMPATABILITY:
Turbine engines using synthetic engine lubricating oils should use a Mil-C-6529C   corrosion preventative concentrate. Turbine engines using lubricants compatible with mineral based fluids should use ROYCO 483 corrosion preventative.
