Non-Detergent Oils may be implemented as lubricants in antique engines, small engines, or industrial machinery. Some of the applications include air compressors and other types of compressors and any machinery requiring a refined, non-detergent oil.
SAE 20 Grade Oils are simultaneously classified as ISO VG 68 oils. These oils have a midpoint kinematic viscosity of 68 mm2/s, also referred to as centistokes (cSt). The midpoint is derived by taking the average of both the minimum and maximum kinematic viscosities. In the case of ISO VG 68 oil (also SAE 20 oil), those numbers are 61.2 cSt and 74.8 cSt, respectively. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
