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 637 synthetic lubricant is blended from polyglycol-based products for use in natural gas rotary screw compressors. The resistance to thinning out by hydrocarbon dilution allows this lubricant to maintain the proper operating viscosity which in turn extends drain intervals and parts life. This unique blend is specifically treated with rust and corrosion inhibitors, oxidation control agents, anti-wear compounds, and hydrogen sulfide inhibitors.
