Like many people, I'm sure, I'm trying to identify the "benchmark" tests that all good oils are subjected to, and then learn how to interpret those results. Do these "standard" tests exist?
For example, I saw a post that was comparing Amsoil oils and the poster referred to: Kinematic Viscosity @ 100ºC, cSt (ASTM D 445), Kinematic Viscosity @ 40ºC, cSt (ASTM D 445), Viscosity Index (ASTM D 2270), CCS Viscosity, cP @ (ºC) (ASTM D 5293), NOACK Volatlty, %wt loss (g/100g) (ASTM D 5800), and High-Temperature/High-Shear Viscosity @ 150ºC, 1.0 X 106 s.-1, cP (ASTM D 5481). When I look at the specs for different oils, I see similar verbiage (but not always verbatim).
In short, I'm trying to learn how to best compare oils in a systematic fashion. I'll accept whatever advice anyone has to offer as a starting point!
Thank you,
Ed
