ISO VG 100, AGMA 3, SAE 30 Oil

ISO VG stands for International Standards Organization Viscosity Grade. This classification is almost exclusively limited to industrial lubricants. AGMA stands for the American Gear Manufacturers Association - this specification is dedicated to gear oils. SAE stands for the Society of Automotive Engineers. Naturally, this specification is most often reserved for automotive lubricants, however, there are also SAE Gear Oils.

Some oils that may be classified as ISO VG 100 oil may also be classified as an AGMA 3 and/or SAE 30 oil. In other words, these oil classifications are interchangeable in their applications - however, it is best to consult OEM specifications to determine which lubricant specification is recommended for use.

ISO VG 100/SAE 30/AGMA 3 lubricants for industrial and (few) automotive applications are commonly employed in hydraulic systems, moderately-loaded and heavily-loaded gearboxes, food industry machinery, slide ways, and some air and gas compressors.

ISO VG 100 oil has a midpoint kinematic viscosity of 100 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 100 oil, those numbers are 90.0 cSt and 110.0 cSt, respectively. SAE 30W oil has a minimum high-temperature kinematic viscosity of 9.3 mm2/s (cSt). AGMA 3 lubricants have a minimum viscosity of 90 mPa.s and a maximum viscosity of 110 mPa.s. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
