Non-Detergent Oils generally have very limited and specific applications. Some of these applications include the lubrication of air compressors and other industrial machinery. However, these oils are sometimes used to lubricate the internal components of antique automobile engines (without filters). Additionally, small gas engines such as those employed in lawnmowers may benefit from the employment of Non-Detergent lubricants.
ISO VG 32 oils that are also Non-detergent oils have a midpoint kinematic viscosity of 32 mm2/s (which is sometimes referred to as 32 cSt, or centistokes).
