McDonnell Douglas Specs

DPM 670

DPM 670 corresponds to Royco 482.

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.

For more information see Royco 482
