Web6 okt. 2024 · When discussing lubricants, there are several different designations of viscosity, such as ISO VG, AGMA, SAE Engine Oil, and SAE Gear Oil. Lubricants can also be graded in cSt (kinematic viscosity in centistokes), and SUS (Saybolt Universal Seconds) just to name a few. Webmineral oil is a mixture of tens of different oil molecule types, each with a different viscosity! In this case, what we measure as viscosity is the bulk average viscosity of the mixture. This will be a value somewhere between the highest and lowest viscosity oil …
