All of our Royal Lubricants are 100% OEM compatible and are formulated to achieve the best possible results in each application.


Our Royal Lubricants Royco 639 synthetic lubricant is a polyglycol-based product developed specifically for use in enclosed gear, bearings, and compressors where conditions require the unique properties of these fluids. Better wear protection, thermal and oxidation stability, and reduced sludge and deposit build up insure enhanced performance when compared to petroleum-based lubricants. This lubricant is incompatible with petroleum oils. Care should be taken to make sure the two types of oils are not mixed.
