Air-compressor oil is usually a synthetic oil that does not contain detergents commonly found in motor oil. Air-compressor oil is manufactured specifically for use in lubricating the ball bearings inside a compressor and is generally the recommended choice by manufacturers of air compressors. A synthetic oil also helps reduce carbon deposits within the compressor.
