Oil... how does it work? [split]

oh cSt

Check this out:
The viscosity of a fluid is highly temperature dependent and for either dynamic or kinematic viscosity to be meaningful, the reference temperature must be quoted. In ISO 8217 the reference temperature for a residual fluid is 100oC. For a distillate fluid the reference temperature is 40oC.

• For a liquid - the kinematic viscosity will decrease with higher temperature

All those cSt figures were taken at the same temperature in the chart above if I understand it correctly so temperature shouldnt be a factor.

It’s taking different grades, bring them up to the same temperature and rating them on their fluidity.
