quote:Hi, You asked two questions. For relating cSt, cP, mPa-s, SAE and SUS viscosity measurements, refer to Bobistheoilguy home page. Viscosity is a measurement of resistance to flow. So, one natural way to measure viscosity is to make it flow through an opening. Measurement device used in this type of viscosity measurement is a timer such as a stop watch. Jae

Originally posted by PaJohn: Ahhh, now I get it. I just find the Kinematic Viscosity @ 100°C for the specific oil and depending on where it falls on the chart makes it low or high in that grade. For example, Amsoil S2K 0W30 is [email protected] so it's about in the middle of the 30 grade. Do I have that right?
