Can somebody cure my ignorance? The numbers for cSt @100 and 40 degrees, higher numbers better for both?
If you were choosing an oil based on these(and other factors, of course) would you choose one with higher or lower cSt numbers.
The same for Viscosity index.
Thank you, and forgive my lack of knowledge!
