MN-7.5 oil is currently used in high-speed angle gears. In order to ensure reliable starting and operation of such gears, the oil must have a relatively flat viscosity-temperature curve, high thermal-oxidation stability, good antiwear and extreme-pressure properties, etc. Such properties are provided by the use of various functional types in the MN-7.5 oil. During operation under marine conditions, seawater may get into the oil and produce "salinization" of the oil. This paper presents results of an investigation in which the effect of seawater and subsequent washing on the oil quality was studied. It is demonstrated that MN-7.5 oil that has been salinized (salt-contaminated) in service can be washed satisfactorily if the oil temperature is increased to 70-75 degrees C. Repeated washings of the salinized MN-7.5 oil with distilled water do not harm the basic service properties of this oil.
