ISO and SAE are standardized specifications that define oil weight. Both organisations provide test standards to allow the ability to reliably compare published filter ratings among manufacturers. There is no significant difference between ISO (International Standards Organisation) or SAE (Society of Automotive Engineering). This number is critical because a lubricant’s viscosity is the single most important factor when selecting the right oil for your machinery. International Standards Organization Viscosity GradeISO VG stands for “International Standards Organization Viscosity Grade” and is reported in numbers ranging from 2 all the way up to 1500. ISO Grade 150, Mineral oil LUBRIPLATE APG 80W-90 lubricant was designed specifically as an extreme pressure gear lubricant for use in automotive type hypoid gears and high offset gears operating under high-speed, high-performance conditions. Eurol Syntan EP ISO-VG 220 has excellent anti-oxidation, anti-wear, anti-rust and high pressure properties. Eurol Syntan EP ISO-VG 220 is a fully synthetic oil based on poly-alkylene glycols for the lubrication of all types of heavily loaded gearing, like hypoid and worm gears. The grade is a literal measurement of the oil’s ratio of absolute viscosity in centipoise (a unit of measurement) to the density, also known as centistoke. Thus, an oil or lubricant with a viscosity grade of 220 is thicker and more solid-like than an oil with a VG of 100 or 68. In the case of ISO VG 220 oil, those numbers are 198 cSt and 242 cSt, respectively. The midpoint is derived by taking the average of both the minimum and maximum kinematic viscosities. ISO VG 220 oil has a midpoint kinematic viscosity of 220 mm2/s, also referred to as centistokes (cSt). Edit:If you must consider an automotive gear oil due to availability and price issue, please consider a 85W140 with a *C closer to 242 cSt. No, you can’t use automotive SAE 75W90 whose *C is typically 100 – 105 cSt, i.e equivalent to ISO 100 industrial gear oil and it is 2 viscosity grades thinner than that of ISO 220. What is the equivalent viscosity of ISO-VG grade gear Lube?Įquivalent Viscosity of ISO-VG Grades at 40oC and SAE Gear Lube Grades ISO-VG Grade SAE Gear Lube Grade 46 75W 100 80W-90 220 90 460 85W-140 1500 250 Equivalent Viscosity of ISO-VG Grades at 40oC and AGMA Gear Lube Grades ISO-VG Grade AGMA Gear Lube Grade Regular EP 46 1 68 2 2 EP 100 3 3 EP 150 4 4 EP 220 5 5 EP 320 6 6 EP 460 7 7 EP 680 8 8 EP Oil ISO VG 220 oils (also known as AGMA 5 oils, SAE 50 oils, and 90WT Gear oils) are applicable in various industrial applications that include gearboxes, hydraulics, compressors, and slideways. I understand that it’s basically 90 weight oil. I cannot find any oil in my area that says ISO 220. I have a gearbox that says to use ISO 220 gear oil or equivalent. I have asked the OP to either respond or the thread gets locked. Viscosity read across charts are usually based on 95VI oils and the ISO 220 does align with SAE 90.
